hello, you can also get to the troubleshooting data manually while in safemode by entering about:support into the address bar.

How do I copy the data and enter it into my post?

there's a button "copy raw data" on top of the about:support page - you can paste that into the troubleshooting section when you cretae a new question on support.mozilla.org or simply paste it into a reply of one of your existing questions...

There is a section for Crash Reports. It says non submitted for 3 days...

why not? I have been Force Quitting FF all afternoon, because it is becoming Not Responding during startup. That should generate a crash report.

In Firefox Safe mode these changes are effective:

• all extensions are disabled (about:addons)
• default theme is used (no persona)
• userChrome.css and userContent.css are ignored (chrome folder)
• default toolbar layout is used (localstore-safe.rdf file)
• JavaScript JIT compilers are disabled (about:config page: javascript.options.*jit)
• hardware acceleration is disabled (Options/Preferences > Advanced > General)

• plugins are not affected
• preferences are not affected
