Firefox keeps crashing? Here's how to fix it

Firefox is now five, however if, like many, you've found yourself having to leave your favourite browser because of constant crashing there are plenty of ways to get your Firefox groove back and save yourself from Mozilla hell.

Here are three steps to insuring you can surf the Web with the friendly fox once again:

Disable all your apps

With so many Plug-ins available for the browser, one of the reasons you could be experiencing crashes is that one of them has gone rogue. If this is the case, the best way to find out is disable all your apps and then slowly turn them back on to see which one is causing the issue.

Safe Mode

Firefox comes with a Safe Mode for exactly this reason - trying to fix bugs. buried within the inner workings of Firefox is a handy box that when accessed will allow you to reset your browser to its "factory" settings.

On the Mac you can access this via the Terminal application in Utilities (/Applications/Firefox.app/Contents/MacOS/firefox -safe-mode) while on the PC you'll find it by accessing the Run command within the Start Bar ("C:Program FilesMozilla Firefoxfirefox.exe" -safe-mode)

Once you've run the application you get to disable all the add-ons in one swoop, reset toolbars and controls, reset bookmarks back to the Firefox defaults, reset all user preferences to Firefox defaults and even restore the default search engine, giving you a fresh start.

Starting from scratch

If none of the above has worked, you've got to take drastic action and make your computer believe that you've never seen or heard of this Firefox browser program. First off you've got to delete it completely.

Unfortunately just deleting or uninstalling the browser from your Mac or PC won't solve your problems, as the browser buries itself into your computers profile and user settings. It's like pulling out a weed, you've got to get right down to the roots to clear out the infection.

Mac

For Mac users drag the Firefox app into the Trash and then remove the Library/Application Support/Firefox folder. This will remove Firefox completely, your bookmarks, browser settings, plug-in details the lot. 

PC

For the PC it's just as simple. First remove the program via the "Add or Remove Programs" tool then delete the Firefox Installation directory located at C:Program filesMozilla Firefox

Reinstall

Now you've removed all the traces of the browser on your computer you simply visit the getfirefox browser website, download the right version for you and reinstall.

If you've done the above, your browser will reinstall and you'll be able to use Firefox like you did before you became a constant crash victim - hopefully for another 5 years.
