This problem started yesterday, though I haven't downloaded anything or changed anything. I have tried reinstalling Firefox and Yosemite, repair permissions, disable all plugins/add-ons, but still no success. Every other program and browser work. Only Firefox is having this problem. Please help me fix. Thanks.

Chosen solution

Never mind, I found my own solution. I imported bookmarks, etc from Firefox into Safari. Saved bookmarks as an HTML file from Safari (if you can save the bookmarks in Firefox that's better, but I couldn't since Firefox was frozen). Then AppZapped Firefox (uninstalled) and downloaded Firefox again and reinstalled it. Then I imported the bookmarks I had saved. Everything is working fine now.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. Is the problem still there?


Start your Computer in safe mode with networking. Then start Firefox. Try Safe web sites. Is the problem still there?
