Each time my computer is restarted, I am asked to install an add-on when I open Firefox. I have searched the forums here and tried deleting the extension files as recommended. I've also tried the "refresh" Firefox option in settings as well as uninstalled, re-downloaded, and reinstalled Firefox. Is there anything else I can try, aside from just finding a new browser altogether?

There is software like Advanced SystemCare with its Surfing Protection feature that can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

You can check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
