It sounds like there is a problem with your profile. Use these instructions to create a new, blank profile. '''https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles''' '''Windows: 32-bit''' C:\Program Files\Mozilla Firefox\firefox.exe -p '''64-bit''' C:\Program Files (x86)\Mozilla Firefox\firefox.exe -p '''Mac:''' Navigate to '''/Applications/Utilities.''' Open the Terminal application. In the Terminal application, enter the following: /Applications/Firefox.app/Contents/MacOS/firefox-bin -p '''Linux:''' In '''Terminal''' run: firefox –P For users who have one or more builds from mozilla.org this will not work. It would be best to have the full path so if you had placed the untared contents in a folder in /home it would be /home/<username>/foldername/firefox/firefox –P An easy way would be not to do it in a terminal but in say a launcher since you have to point it to the firefox script in Firefox folder you can then add –P on end. You can also have the exact "profilename" after the -P so Firefox will start with that Profile.
