How to Start Firefox in Safe Mode

Firefox has a mode for troubleshooting purpose and that mode is "Safe Mode".

This Firefox Safe Mode can be started in 5 different ways. In this post, we are gonna see all those ways. Let's get started.

Start Firefox in Safe Mode

1
  • Launch the Firefox browser.
  • Click on Menu (Hamburger) icon and select Help (Question mark) icon. It opens up the Help menu.
  • Click on "Restart with Add-ons Disabled...".
  • In the popup, click on "Restart". Now you can see the Firefox Safe Mode popup.
  • Firefox restart popup
  • Click on "Start in Safe Mode" to launch the Firefox in safe mode.
  • Firefox Safe Mode popup

In case, you do this method with more than one Firefox windows already opened, then it will relaunch all those Firefox windows in the safe mode.

You've probably had a Firefox shortcut on your PC now. If not, just go to this location:

C: > Program Files > Mozilla Firefox

And, right click on the Firefox application and select Send to > Desktop (create shortcut).

Now you have a Firefox shortcut on your desktop.

Here are the steps you need to do now:

  • Press and hold the Shift key and double click the Firefox shortcut.
  • Now you can see the Firefox Safe Mode popup. Click on "Start in Safe Mode" button.

Important Note

When you try this method, make sure there is no other Firefox window is already opened.

If any other Firefox windows are already opened on your PC, then this method will launch just another Firefox window, not launch Firefox in safe mode.

This same condition applies for all the remaining methods (3,4 and 5) in this post.
