Write notes in a new tab and save them locally with the TextNotes extension for Firefox

Found something interesting and want to save it for future reference? You could save the web page, or copy the content and save it in Notepad, or a cloud-based note taking service. But if you would like to save the note directly in Firefox, you’ll probably like the TextNotes extension.

Before you get your hopes up and think this is an add-on that saves notes to specific tabs, let me tell you that it doesn’t. Click on the extension’s button on the toolbar and a new tab opens. This is TextNotes’ interface, and the page is divided into two panes. The one on the left is the tree panel which lists the notes that you have added, select a note and its contents will appear on the right pane.

Well, there is no note available to begin with, so let’s add one. Click the + button above the tree and a new blank note is created. Place the cursor in the right pane and type away. TextNotes will automatically save the note. Where does it save it? The extension does not rely on cloud services, as I hinted earlier it is an offline add-on. Your notes are saved directly in your browser’s storage (in your current profile).

There is another way that you can create new notes. Select some text on a web page, access the right-click menu, and choose the option that says “Add Selected Text to TextNotes”. This creates a new note which contains the text, but it doesn’t include the title or the URL of the tab/page that the content was saved from.

You can open TextNotes with a hotkey; Ctrl + Alt + O. Don’t want to open it in a new tab? Use Ctrl + Alt + P, or click the toolbar button while holding the Ctrl key, to open the interface in a new window.

The hotkeys can be changed from Firefox’s add-ons page: Add-ons > Manage Extension Shortcuts > TextNotes.

You can trash notes, and the deleted notes are stored in the add-on’s built-in trash bin, from where they can be recovered instantly if required. Drag and drop notes to rearrange their order. Right-click on the sidebar to create a new note, add a separator to manage a collection of notes or to delete a note.

TextNotes has a feature called hyperclicks, which are clickable hyperlinks or URLS, paste the link in a note, and you’re good to go. To use a saved link, hold the Ctrl key and the left mouse button for a few seconds, that’s a Ctrl + long-click. This action opens the link in a new tab in the foreground. To open it in a background tab, make sure that Caps Lock is enabled while you Ctrl + long-click.

Since TextNotes does not support cloud-based synchronization of its own, you will have to rely on Firefox sync. But, in order to prevent loss of data, you may want to save your notes manually. Click on the three-dot icon in the top right corner of the add-on’s interface. Select Preferences and a pop-up window appears with 3 options. Hit the Save button to store your notes as a TN (compressed document) file. Or you can save the content directly to a plain-text file, which you can open with Notepad or any text editor of your choice.

The TN document is useful if you want to Load (import) it back to TextNotes. If you want cloud-support, you can save this file to your online storage account, as a backup. The add-on’s menu also has a Help file which explains how TextNotes works.

uBlock Origin de Raymond Hill

În sfârșit, un blocant de reclame eficient. Folosește procesorul și memoria foarte puțin.

  • Despre această extensie

Un blocant (paravan) eficient: folosește foarte puțin procesorul și memoria și totuși poate încărca și aplica mii de filtre în plus față de alte paravane populare.

Utilizare: Butonul mare de pornire/oprire în fereastra paravanului este pentru a activa/dezactiva uBlock pentru site-ul curent. Funcția este valabilă doar pentru site-ul curent, nu la nivel global. Flexibil, mai mult decât un „blocant de reclame”: acesta poate citi și crea filtre din fișierele de gazde (hosts).

  • În mod implicit, aceste liste de filtre sunt încărcate și aplicate:

– EasyList
– Lista serverelor de reclame a lui Peter Lowe
– EasyPrivacy
– Domenii malițioase

  • De asemenea, mai sunt disponibile și alte liste precum:

– Lista îmbunătățită pentru urmărire a lui Fanboy
– Lista de gazde a lui Dan Pollock
– Lista de reclame și urmărire hpHosts
– Gazdele MVPS
– Spam404

Desigur, cu cât sunt mai multe filtre active cu atât mai mult este utilizată memoria. Totuși, chiar și după adăugarea în plus a două liste Fanboy și lista de reclame și urmărire hPhosts, uBlock₀ tot folosește mai puțină memorie decât restul paravanelor. De retinut că odată cu selectarea în plus a unora dintre liste se poate ajunge la afectarea aspectului site-urilor — în special listele care sunt în mod normal liste de gazde.

Fără listele prestabilite de filtre această extensie nu face nimic. Așadar, dacă totuși vreți să contribuiți, gândiți-vă la persoanele care muncesc să întrețină aceste filtre pe care le utilizați, care sunt oferite pentru utilizare gratuită.

Acest supliment trebuie să:

  • Să citească și să modifice setările de confidențialitate
  • Să acceseze filele browserului
  • Să stocheze un volum nelimitat de date pe partea de client
  • Să acceseze activitatea browserului în timpul navigării
  • Să îți acceseze datele pentru toate site-urile web

How to Calculate the Sum of Squares in Excel

Start a new column anywhere in an Excel spreadsheet and label it. It’s here that we’ll output the solution of our squares. The squares don’t have to be next to each other, nor does the output section; it can be anywhere on the page.

Type the following formula into the first cell in the new column: =SUMSQ(

From here you can add the letter and number combination of the column and row manually, or just click it with the mouse. We’ll use the mouse, which autofills this section of the formula with cell A2.

Add a comma and then we’ll add the next number, from B2 this time. Just type in B2 to the formula, or click the appropriate cell to autofill it.

Close the parenthesis and press “Enter” on the keyboard to display the sum of both squares. Alternatively, if you can keep going here, adding additional cells by separating each with a comma within the formula.

To apply the formula to additional cells, look for the small filled square in the cell that contains the solution to our first problem. In this example, it’s C2.

Click the square and drag it down to the last row of number pairs to automatically add the sum of the rest of the squares.

Finding the Sum of Squares for Just a Few Cells

In our “Sum of Squares” column we created in the previous example, C2 in this case, start typing the following formula:

=SUM((A2)^2,(A3)^2)


Alternatively, we can just add the numbers instead of the cells to the formula, as either way gets us to the same place.

That formula looks like this:

=SUM((9)^2, (29)^2)

You can alter these formulas as needed, changing the cells, adding additional numbers, or finding the sum of squares that aren’t even in your workbook, for example. And while it’s easier to follow along with the above tutorial, using the SUMSQ formula, to find the solution for multiple squares, it’s often easier to just type out a quick formula like this if it’s not something you’ll be repeating throughout the workbook.

How to Get a Spotlight-Style Search Bar on Windows 10

On a Mac, a system-wide search and launch feature called Spotlight is only a shortcut away with Command+Space. Thanks to PowerToys, Windows 10 can have a similar search and run bar as well when you hit Alt+Space. Here’s how to set it up.

The Power of Microsoft PowerToys

With a PowerToys module called PowerToys Run, you can press Alt+Space and see a quick pop-up search bar appear from anywhere in Windows 10. Once it appears, you can search for applications and documents and run or open them quickly. To get this handy search bar, you’ll need to install PowerToys, a free collection of Windows 10 utilities from Microsoft.

Once PowerToys is installed, launch PowerToys Setup and select “PowerToys Run” in the sidebar. Then make sure that “Enable PowerToys Run” is switched on.

After that, close PowerToys Setup and try out your new search bar. Press Alt+Space and a minimalist search bar will appear in the center of your screen.

Once you type in a search, you can hit Enter to immediately launch (or open) the first result, or you can choose from the results in the list with your mouse or cursor keys and hit Enter.

You can also use several “power user” buttons that appear beside each result to perform certain handy actions. Here’s what they do.

  • Copy icon: This copies the file path to the clipboard (only applies to documents).
  • Box with a Shield: This runs the app as administrator (only applies to programs).
  • Folder: This opens the containing folder, revealing the file or app’s location in File Explorer.
  • C:\ Box: This opens a path to the file or document in a command prompt.

But don’t just think of PowerToys Run as a glorified search bar. You can also use the PowerToys Run box as a replacement for the Windows+R “Run” dialog. Just pull up the box with Alt+Space, type a command, and hit Enter, and the program will run instantly.

It’s just one more way that PowerToys delivers a more convenient and powerful Windows 10 experience. If you like PowerToys Run, it’s worth taking the time to explore other PowerToys features. New ones are often added to the suite over time.

How to Disable Internal Laptop Keyboard in Windows OS

Sometimes, due to any reason you may want to disable or block your internal Laptop keyboard. In this guide I am going to show you how to do that in Windows OS without installing any third-party software or application. There could be a number of reasons why you would want to disable the Internal Keyboard. Here are some of the most common scenarios that users usually face:

  • Laptop keyboard is malfunctioning and is not usable anymore
  • You want to use an external keyboard instead of the built-in one
  • Some keys are malfunctioning, causing problems while operating the PC
  • Internal keyboard wiring is faulty and is automatically deleting files or sending commands

Sometimes, you don’t want to visit the local repair store because it’s just not worth it. The repair process can be cumbersome and fixing the laptop might charge you a lot of money. In some scenarios, it is just easier to plugin an external USB Keyboard and use it instead. We are going to explore a way to turn off the keyboard without installing any software on your PC. Windows offers built-in utilities and tools to achieve that within a matter of minutes.

Steps to Disable Keyboard

The procedure is very simple. You can easily disable or block any device including Keyboard, Mouse, Touchpad, USB storage or any other device with the Local Group Policy editor. Group Policy editor is a built-in Windows utility that allows you to control every aspect of your Windows PC. If you know how to properly use this tool, it will give you super power over your PC.

Follow the steps below to turn off your Laptop keyboard by changing the Group Policies:

  • Open the ‘Run’ window and type gpedit.msc and press Enter.
  • Now, under the Computer Configuration, traverse to the following path: Administrative Templates > System > Device Installation > Device Installation Restrictions.
  • Under the list of policies, you need to select the one that says Prevent Installation of devices that match any of these device IDs and then double-click on it.
  • Next, select the Enabled option and click on the Show button to open the Contents window. In this window, you will need to enter the Device ID for the Keyboard you wish to disable.
  • Now, as you can guess, you need to extract the device ID of the keyboard you want to block. To do that, you need to go to the Device Manager. To open Device manager, you can search in the Windows search bar and you will see it in the search results.
  • In the Device manager, go to the Keyboard container, right-click on the Keyboard that needs to be blocked and click on Properties.
  • Now go to the Details tab and select hardware ids from the drop down menu.
  • Afterwards, select the top most hardware id and, right-click on it and select Copy.
  • Go back to the Show contents window of the Group policy editor and paste the hardware id of the keyboard and click OK.
  • Once that’s done, the final step is to uninstall the driver of the Keyboard device from the Device manager. In the Device manager, right-click on the Keyboard and click on Uninstall Device.
  • That’s all you need to do. Once you have completed all these steps, it is time to test the new policy setting. To test it, simply restart your PC and try using the keyboard keys. If everything went right, the keyboard will not work. Now you can plugin an external keyboard and use it instead.
  • How to Revert the Policy Setting

    If ever in the future you need to revert the configuration, it can be done very easily. Go to the policy setting and instead of the Enabled option, select Not Configured. Then restart the PC. This will revert the policy setting and now you will be able to use your keyboard just like before.That’s all you need to do. Once you have completed all these steps, it is time to test the new policy setting. To test it, simply restart your PC and try using the keyboard keys. If everything went right, the keyboard will not work. Now you can plugin an external keyboard and use it instead.

How to Restrict USB Read and Write Access in Windows 10

In many situations you might need to restrict USB storage Read and Write access on your Windows 10 system. In this guide I am going to show you a very easy way to do that without typing any commands. Fortunately, Windows gives you granular control over your devices without having the need to install any third party software.

Here are some of the most logical reasons you might want to control USB device access on your PC:

  • To safeguard your PC from malware and viruses. USB devices are the primary source of malware infections
  • To protect your data from getting stolen by anyone with physical access to your PC
  • Not letting someone Live Boot another Operating System and get into your HDD storage

There can be various reasons, and honestly, it is very likely that you may face such a situation at some point. These kind of attacks are more occurring than you might imagine. Any newbie hacker or script kiddie can easily get into your system with just a USB stick.

Restrict / Disable USB Read and Write Access via Group Policy

We are going to look at two ways to disable USB device Read and Write access in Windows 10. Windows comes with Group Policies that control the working environment for Users and Computer accounts. You can easily control your USB device’s permissions by configuring a group policy. Here are two scenarios that you can control:

Denying Access for All Users (Method-1)

Restricting USB devices for all users can be done with a few very easy steps:

  1. First you need to open the Local Group Policy editor. To do that, go to the ‘Run’ and type gpedit.msc and click Enter.

2. One the group policy editor opens, you will see two options: “Computer Configuration” and “User Configuration”. Open the User Configuration by double-clicking on it:

3. In the next Window, browse to the following path: Administrative Templates > System > Removable Storage Access.

4. In the next Window you will see a list of Group Policy settings that includes different types of devices including CD and DVD, Floppy Drives, Tape drives, WPD devices and Removable Disks. The ones that we are interested are Removable Disks. From these settings you can control both Read / Write permissions for USB flash drives. Let’s go ahead and Deny both the Read and Write Permissions:

5. Double click on both the permissions one by one and select the Enable option to enforce these restrictions. Click ‘Apply’ and then ‘OK’.

6. After applying these restrictions, you can check whether the settings have applied correctly or not. To check that, insert a USB flash drive into your system’s USB port and try to open it from ‘My Computer’. It should give the following message:

7. If you see this message, that means the policy setting has applied correctly and you have successfully restricted access to USB drives for all users. To remove the policy setting, simply go back to the settings and select Not Configured. It’s that simple.

Denying Access for a Specific User (Method-2)

If you need to restrict USB access for a specific user that uses your computer and not yourself then it’s also possible. The way to do it is a bit different than the method explained above. With this method, you can also enforce these restrictions for Administrators and Non-Administrators separately. Here are the steps to do it:

  • First you need to open the Run dialog box and type mmc.exe and press Enter. This will open the Microsoft Management Console.
  • In the Console Window, click on the ‘File’ menu and select Add/Remove Snap-in.
  • In the list of Available Snap-ins, select Group Policy Object Editor and click on Add.
  • A window of Group Policy Wizard will pop up. Here you will have to click the browse button to be able to select the User groups of your choice.
  • In the next window, click on the Users tab and select the user for which you want to impose the restriction. Click OK and then click ‘Finish’.
  • After clicking OK, you should see the Group Policy Editor window just like we saw it in the first method. Simply double-click the container and you will see the same Group policy settings that were described in the first method.
  • Now you have to follow the same path: User Configuration > Administrative Templates > System > Removable Storage Access and apply the same Read / Write Deny policy setting on Removable disks. Once it’s done, you can test the policy setting by logging in from that particular User and plugging in the USB storage device. You should see the same error message.

Opera adds the Play Music sidebar to Opera Browser for Spotify, Youtube and Apple

Opera Software released a new Developer version of its Opera web browser. The new version introduces support for music playback from the browser’s sidebar. Opera Developer is the cutting-edge development version of the browser. Features are introduced in the browser first before they land in Beta and Stable versions.

If you do like to play music in your browser, you may have noticed that it usually involves juggling between different windows, e.g. different browser tabs in a single browser, or, in the case of a dedicated desktop music player, between different program windows.

Some browsers introduced global media controls, e.g. Firefox and Chrome, to control playback in that browser without switching windows. While that is useful to some, it still requires accessing the music service’s interface for some operations, e.g. searching for music, playing a different playlist, or adding new songs to the existing playlist.

The Opera browser implementation is controlled via an icon in the browser’s sidebar. A click on it display the supported services — currently Apple Music, Spotify, and YouTube Music — that you may access from the sidebar. You can resize the interface and pin it if you want to make it stick to the screen.

A click on a service opens its startpage. What happens next depends on that service, as you may need to sign-in to an account to start using it. A click on YouTube Music displays the service’s startpage and options to play one of the listed playlists, e.g. top 100 charts, or to search for music

A click on the play button starts playback right away. Some services may display ads to free users, and these are played even if you have enabled Opera’s built-in adblocker.

Music playback continues even if the sidebar interface is hidden; Opera indicates playback by changing the icon of the player. If a site is opened that plays music or audio as well, music playback is paused automatically by the player to avoid that multiple sounds play at the same time in the browser. Playback is resumed once all other audio stops playing in the browser.

Opera users may customize the sidebar; they may hide any service that they don’t use to avoid clicking on these unintentionally. Click on the three dots at the bottom of the sidebar and toggle the options to hide them in the interface. You can also hide the entire sidebar if you don’t use it.

Enable or Disable Programs and Apps Automatically Restarting with Windows 10

In Windows 10, you might have noticed that sometimes if you don’t close a running program or UWP app and you restart or sign out, the program or app automatically launches once you sign in. Actually Windows 10 comes with a special feature called “Windows Restart Manager” which detects programs and apps (including UWP or Store apps) running in the operating system and if the user doesn’t close those apps and restarts the computer or logs off, this Restart Manager feature automatically restores the previously running programs and apps after reboot or sign in.

To take benefit of this feature, 3rd party programs and apps need to register as restartable app with Restart Manager functionality. Now-a-days many programs such as Mozilla Firefox, etc are utilizing this feature to automatic restart once user restarts or signs out. Don’t confuse this feature with automatic startup programs. Many programs and apps add their entries to Windows startup list and automatically launch as soon as the user logins to Desktop. You can manage (enable/disable) those startup programs.

Windows Restart Manager is a different feature. It restarts those programs and apps which were registered to take benefit of this functionality and were running when the user restarted his device. It doesn’t matter whether those programs and apps have their entries in Startup programs list.

Windows 10 allows users to enable or disable this functionality using Settings app. Previously this functionality was tied with finishing setting up the device after Windows Updates installed in the device.Now the newer versions of Windows 10 (version 2004 and later) come with a dedicated and separate option to turn on/off automatically restarting programs and apps after reboot or sign out.

If you also want to enable or disable this functionality in Windows 10, following steps will help you:

1. Open Settings app from Start Menu. Alternatively, you can press WIN+I keys together to open Settings directly.

2. Now click on Accounts icon in Settings app and then click on Sign-in Options tab present in left-side pane.

PS: Alternatively, You can directly launch this page using “ms-settings:signinoptions” command in RUN dialog box

3. Scroll down to bottom and you’ll see “Automatically save my restartable apps when I sign out and restart them after I sign in” option under “Restart apps” section.

If you want Windows 10 to restart programs and apps after sign in, set the option to ON.

If you want to prevent/restrict Windows 10 from automatically restarting programs and apps after you sign in, set the option to OFF.
