Clean SlateFireFoxMozillaReset Profile

You might ask yourself: Where are the FireFox extensions and plugin folders located on OSX Mac?

Of perhaps you’re asking yourself: How to I get to use my FireFox within it crashing?



So, it’s best to not delete any files right away. Just move them to a temp folder or keep them in the Trash bin.


Verify these folders:


/Library/Internet Plug-Ins/




Get your Profile folder. Open FireFox, got to Help->Troubleshooting Information


/Users/yourusername/Library/Application Support/Firefox/Profiles/yourprofilefolder/extensions


Note: Some extensions create subfolders of their own with data and logs which might need to be cleaned manually.


Be sure to Close / Restart your browser after making changes if you want to test the results.
