If you want to record audio in Windows 11, Microsoft provides a native app exclusively for recording. All you need to do is just access this application and start to record audio.
To make a copy of all your saved passwords, bookmarks, and add-ons, back up your Mozilla Firefox profile to a safe location either on your internal or your external storage. Later, you can restore this backup to bring all your items back into the browser. The way this works is that you copy your Firefox profile folder to a location you deem safe.
This location could be on the same computer, another computer, external storage, or even cloud storage. Later, when you want your backed-up items back, paste the folder in your profile location and Firefox will import all your data.
