How to Start Firefox or Internet Explorer in Safe Mode?

In this post, we’ll see:

A Quick Introduction to Safe Mode

Firefox and Internet Explorer have a mode for troubleshooting, and that mode is safe mode.

Start Firefox in Safe Mode

You can launch the Firefox web browser in safe mode in five different ways.

Before we see the methods, let’s see some important things:

  • If you’ve any other already opened Firefox windows while following Method #1 and #2, then those windows too will get launched in safe mode.
  • Before trying Method #3, #4, and #5, make sure no other Firefox windows are already opened. Otherwise, those ways will not open Firefox in safe mode, and they’ll open normal Firefox windows.
  • To get out of safe mode, close the safe mode windows.

With that said, let’s see the methods.

Method #1

  1. Open the Firefox web browser.
  2. Click on the three vertical lines at the top right.
  3. In the menu, hit on Help > Restart with Add-ons Disabled.

  4. In the Firefox Safe Mode pop-up, hit Start in Safe Mode button.

Method #3

  1. Press the Shift key and double-click on the Firefox shortcut.
  2. Now, you can see the pop-up. Click on the Start in Safe Mode button.

Method #4
