Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window to disable all extensions. You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Thank you so much cor-el, I had to resort to the last solution and turned out to be a better facebook. I uninstalled it.

That 'fix' sounds very complicated. Why can't there be an 'auto fix' for us to download. Bad things happen when I start to do these changes myself in SAFE MODE ... It'll screw up the computer .... Always does.

I have always loves FireFox (Mozilla) But THIS problem is going to cause me to stop using this browser.
