Firefox crashes
Hello,
I got following message when I´m opening the application:
Netscape.cfg/AutoConfig failed. Please contact your system administrator.
Error: defaultPref failed: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.setBoolPref]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: prefcalls.js :: defaultPref :: line 91" data: no]
Chosen solution
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: 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.

See:
lockPref("toolkit.telemetry.prompted", true) is a possible source of this error, too. Tested with FF 9.0.1, the parameter seems to be no longer boolean, but integer.
Modified by pfostentreffer
Yes, the toolkit.telemetry.prompted pref is an integer in Firefox 9+
So you need to change it to:
lockPref("toolkit.telemetry.prompted", 2);
