Today, after the last crazy behaviour of my old Firefox profile, I finally decided to migrate it to a new, clean one. Yeah, because when you are experiencing things like: not installable add-ons/extensions, permitted pop-ups not working and pages not refreshing correctly it’s time to change profile.
So, what do you have to do to create a new, better working profile without loosing all your precious informations (bookmarks, history and passwords)?
$ firefox -ProfileManager #create a new profile, leave it as default and close FF
$ cd ~/.mozilla/firefox
$ cp xxxx.oldprofile/bookmarks.html yyyy.newprofile # bookmarks
$ cp xxxx.oldprofile/history.dat yyyy.newprofile # pages history
$ cp xxxx.oldprofile/signons2.txt yyyy.newprofile # autocompletation in forms
$ cp xxxx.oldprofile/key3.db yyyy.newprofile # passwords!!
next, start again Firefox and that’s it! All your history, bookmarks and passwords are there, ad you have now a 100% working Firefox, again.
Note:you can apply this tip to Windows, OSX and all the other platforms supported by Firefox, as well
