There are less drastic ways of fixing a bad Profile, if that is '''''your problem'''''. The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br> '''Note''': ''This will cause you to lose any Extensions, Open websites, and some Preferences.'' To Reset Firefox do the following: #Go to Firefox > Help > Troubleshooting Information. #Click the "Reset Firefox" button. #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish. #Firefox will open with all factory defaults applied. Further information can be found in the [[Reset Firefox – easily fix most problems]] article. ------ Or you can create a new Profile and transfer specific files from the old Profile to minimize personal data loss.<br /> [https://support.mozilla.org/en-US/kb/Recovering%20important%20data%20from%20an%20old%20profile Recovering important data from an old profile] Did either of these fix your problems?
