Firefox just automatically updated on a restart on my mac and now none of my security extensions that WERE WORKING PERFECTLY such a s Adblocker Plus can be turned back on. After 1 hour of frsutration and searching for answers, I am ready to dump what used to be my favorite browser. Anyone else have a solution for this? Thanks in advance.

Are you using the ESR version?


It’s possible that there is a problem with the file(s) that store the extensions registry.

Type about:support in the address bar and press enter.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Delete all extensions* files and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

After, restart Firefox.
