Firefox's Safe Mode is used for troubleshooting and fixing problems. Learn how to get into Safe Mode and what the various options do.

'''Safe Mode''' is a special Firefox mode that can be used to troubleshoot and fix problems. Safe Mode temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes) that might be causing problems. By comparing Firefox behavior in normal mode to its behavior in Safe Mode you may be able to pinpoint the cause of the problem. {for win} {note}'''Note:''' Windows users may be familiar with a Safe Mode for Windows.
