Let’s start.

How to start Firefox in safe mode

Mozilla Firefox has a troubleshooting mode, and this mode is safe mode.

Before we look at the methods, let us see some important things:

  • If you have other already opened Firefox windows when you follow Method #1 and #2, then these windows will also be started in safe mode.
  • Before trying Method #3, #4, and #5, make sure that no other Firefox windows are already open. If not, those ways will not open Firefox in safe mode, and they will open normal Firefox windows.
  • To exit safe mode, close the safe mode window.

In this case, I use Windows 10. Let’s see what the methods are.

Type about:support in the address bar and then press the “Enter” key.

Click the “Start in Safe Mode” button in the Firefox Safe Mode pop-up window.

Method #3

Press the “Shift” key and double-click the Firefox shortcut.

You can now find the pop-up. Click on the “Start in Safe Mode” button.

Method #4

Right-click on the Firefox shortcut (I suggest changing the shortcut name to Firefox safe mode) and select “Properties.”

In the “Target” field, append -safe-mode.

Click on the “OK” button.

In the pop-up, click on the “Continue” button.

From now on, when you open the shortcut, you will see a pop-up.

Click the “Start in Safe Mode” button to start Firefox in safe mode.

Method #5

Open Run Command (Press Windows key and R simultaneously for that). In it, type firefox -safe-mode and then press the Enter key.

Click the “Start in Safe Mode” button in the pop-up.

Note:

You can use the same command in the address toolbar, the address bar of the File Explorer and Task Manager (Hit File > Run new task to use the command). For Command Prompt, you need to use start firefox -safe-mode command.

Then apply the last step in Method #5.

How to reset Firefox

Resetting Firefox will restore the default settings.

Add-ons and customizations are also removed and cookies, browsing history, bookmarks, saved form history, saved logins and passwords, windows and tabs are preserved.

In this case I am using a Windows 10 PC. Here are the steps to reset:

Open the Firefox browser.

Type about:support in the address bar and then press the “Enter” key.

Now you will see the “Refresh Firefox” button at the top right of the screen, which you can find above “Try Safe Mode.” Hit it.

Click the “Refresh Firefox” button in the pop-up.

Note: You will see the “Old Firefox Data” folder on your desktop. You can delete it if you like.

How to reboot Firefox without losing tabs

In this case I use Windows 10.

The usual way to restart the browser is to close the browser and then reopen it.

This way, the browser loses its tabs. But you can restart Chrome or Firefox without it losing any of its tabs, and here’s how:

In the Firefox browser, type – about:restartrequired and then press the “Enter” key.

Click the “Restart Firefox” button to restart.

Note: If you want to do this quickly, then create a bookmark with this command and make it available in the Bookmarks Toolbar.
