Mozilla Firefox Safe Mode

Mozilla Firefox Safe Mode gives us a window to start over (temporarily) by disabling add-ons and resetting (permanently) other settings to defaults. By comparing the performance, we can narrow down and fix the cause of any problem.

There are two ways we can start Firefox in Safe Mode (Windows) –

From Start – All Programs (Programs in Vista) – Mozilla Firefox – Mozilla Firefox (Safe Mode).
From Start – Run – Type firefox.exe -safe-mode. Hit OK. (or “C:\Program Files\Mozilla Firefox\firefox.exe” -safe-mode)
For other operating systems, the paths are:
Linux – use Terminal and type in /path/to/firefox/firefox -safe-mode
Mac OS X – open Terminal and type in /Applications/Firefox.app/Contents/MacOS/firefox -safe-mode

The Safe Mode dialog box pops up.
