uBlock Origin works by using filter lists—sets of rules that tell it which elements (ads, trackers, scripts) to block on a webpage. It can:

• Block ads (banners, pop-ups, video ads, and more).
• Prevent tracking by blocking third-party cookies and scripts.
• Speed up browsing by reducing the number of elements that load.
• Enhance security by blocking known malicious sites and phishing attempts.

By default, uBO uses well-known filter lists, but you can customize it to block even more or whitelist sites where you want ads to appear.

Why Use uBlock Origin Instead of Other Ad Blockers?

💡 Open-source & Transparent → No shady business; it’s maintained by a community.
🚀 Lightweight → Uses less memory and CPU than competitors like AdBlock Plus.
❌ No “Acceptable Ads” → It blocks all ads unless you allow them.
⚡ Advanced Customization → You can create your own rules for blocking content.
🛡️ Privacy-focused → It prevents fingerprinting and data tracking.

Unlike some ad blockers that partner with advertisers to allow “non-intrusive” ads (like AdBlock Plus), uBlock Origin blocks everything unless you explicitly whitelist something.

1️⃣ Easy Mode (Default) – “Set It & Forget It”

• Just install it, and it will block ads & trackers automatically
• Uses EasyList, EasyPrivacy, and uBO filters (default filter lists)
• You can pause it or whitelist websites if needed.

2️⃣ Medium Mode – More Control

• Blocks third-party scripts & frames (often used for tracking)
• Can break some websites but improves privacy.

3️⃣ Hard Mode – Maximum Protection

• Blocks ALL scripts by default (even first-party scripts)
• Requires manual tweaking but offers the best privacy & security.

🔧 To Access Settings:

• Click the uBlock Origin icon in your browser.
• Click the Dashboard (⚙️ icon).
• Adjust settings under the Filter Lists, My Rules, and My Filters tabs.

🔹 Advanced Features

✔️ Element Picker: Lets you manually block specific page elements
✔️ Dynamic Filtering: Controls scripts, frames, and other resources per site
✔️ Firewall-Like Features: Blocks certain types of requests automatically
✔️ Cloud Sync: Sync settings across devices (if using a browser sync).

 How to Install uBlock Origin

1️⃣ Go to the official browser extension store:

• Chrome Web Store
• Firefox Add-ons
• Edge Add-ons
  2️⃣ Click “Add to [your browser]” and install it.
  3️⃣ Done! uBO will start working automatically.

Potential Downsides

🔴 May Break Some Websites → Some sites rely on third-party scripts, so they might not work properly unless you whitelist them.
🔴 Requires Manual Tweaks for Advanced Users → If you use Medium or Hard mode, some sites may require exceptions.
🔴 Not Available on iOS Safari → Apple removed it from the App Store, but alternatives exist (like AdGuard).
