Create a new profile as a test to check if your current profile is causing the problems. See "Basic Troubleshooting: Make a new profile": * https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems. If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

You can find the IDs of the submitted crash reports on the about:crashes page. You can open the about:crashes page via the location bar, like you open a website.

Still not working. I can't run the profile manager. Firefox crashed when I tried. The only way is re-installing FF every time I close the browser after I remove the profile files. The weird thing is that is happening also with Chrome. However, Chrome won't start at all no matter what I do. I deleted the crash reports, so I will post it as soon as I get a new one. I submitted one a few days ago, Thanks for the help
