I have googled (using Chromium which seems fine) and looked at the info Mozilla provide but it isn't that useful. The problem is this. I try starting Firefox (37) and while it's doing that it crashes. If it does appear I get an entirely blank window (not toolbars, nothing.) I've tried running it in safe mode but to be honest, I've no idea how to diagnose the cause from there. Help, please.

Hi Bev,

My first thought is that if it works OK in safe mode, then you may have a plugin or plugins installed that are "breaking" it.

If that's the case my suggestion would be start it in safe mode. Once it's started, go to Tools/Add Ons. Select the Extensions section on the left, then go through each extension listed, and press the Disable button. Once you've disabled them all, close Firefox. Open firefox in the normal mode, and see if it works.

If it works, then it's an extension that's at fault. So enable them one by one, restarting after each and see what makes it go wrong.

If it doesn't work, I seem to remember that there's a setting to reset firefox to it's defaults, but I don't know where that is. Alternatively, Backup your settings, esp bookmarks, uninstall it, delete the firefox config files and files in your /home/YOURUSERNAME/.mozilla directory, reinstall and see if it works. If it does, try importing your bookmarks (I'm not sure if this bit will work - do this at your peril - i.e. you could loose all bookmarks etc).

Hope that helps Steve
