Fire­fox just won’t open any more

Mac Format - - GENIUS TIPS - by Ed Er­cole

QWhen­ever I open Fire­fox 48.0.2, it quits im­me­di­ately. Is this caused by a bug in Fire­fox?

APer­haps, but there are other pos­si­ble causes you should rule out. The first is an old and in­com­pat­i­ble ex­ten­sion, in ei­ther /Li­brary/Ap­pli­ca­tion Sup­port/Mozilla/ Ex­ten­sions or the same path in your Home folder; in Finder, hold å and pick Go > Li­brary. Any which look old or un­wanted should be moved to a folder in Doc­u­ments, which may al­low Fire­fox to start up nor­mally again.

In a new Finder win­dow, lo­cate Fire­fox, then hold å and dou­ble-click the app’s icon to open the browser’s Safe Mode. That mode elim­i­nates third-party ex­ten­sions, themes and ac­cel­er­a­tors you’ve added to the browser. Mozilla pro­vides info about trou­bleshoot­ing in Safe Mode at

Another po­ten­tial so­lu­tion is to re­move Fire­fox’s pref­er­ences file, which is lo­cated in the Li­brary folder within your Home folder. There, open the Pref­er­ences folder and trash the file called­fox.plist. If none of these steps re­solves your prob­lem, you may find Fire­fox’s next ver­sion runs bet­ter.

Fire­fox's Safe Mode dis­ables browser ex­ten­sions, and lets it check ex­ten­sions for com­pat­i­bil­ity and other prob­lems.

Fire­fox ex­ten­sions are in Li­brary at the top of your startup disk and in your Home folder. Re­move un­wanted items.
