This article describes why Firefox may start in Safe Mode when you expect it to start normally.


Firefox not closed completely

If you started Firefox in Safe Mode, it will remain in Safe Mode until Firefox is completely closed. The easiest way to make sure Firefox is closed is to restart your computer. Once your computer starts up again, start Firefox.


Shortcut updated to open Safe Mode

You may have updated the shortcut you use to start Firefox to open it in Safe Mode and forgotten to change it back.

  1. Right-click the icon you use to start Firefox and choose Properties.
  2. Click on the Shortcut tab.
  3. Make sure the Target: box doesn't include -safe-mode at the end. It should only read "C:\Program Files\Mozilla Firefox\firefox.exe" for default installations of Firefox.

Ubuntu

  1. Right-click the icon you use to start Firefox and choose Properties.
  2. If the dialog that opens has tabs, click on the Launcher tab.
  3. Make sure the Command: box doesn't include -safe-mode at the end. It should only read firefox %u for default installations of Firefox.

Safe Mode shortcut on recently used applications list

Windows will list in the Start Menu the applications you have most recently opened. Firefox in Safe Mode may be one of these applications. Try starting Firefox from another shortcut, for example the one under All Programs.
