Whenever Firefox runs into common errors, like high CPU usage, crashes, or network-related errors, a quick solution is to run the browser in Safe Mode. Using Firefox on Safe mode allows the browser to run in its default mode and it can also help you diagnose errors.
If you’re on mobile, there’s currently no method to restart Firefox in Safe mode. But if you’re on Windows, here’re several ways to turn on Troubleshoot Mode in Firefox.

- Click on three horizontal lines in the top right-hand corner to open the menu.
- Then, Click on Help > Troubleshoot Mode.
- A new pop-up window will appear asking if you want to restart Firefox in Troubleshoot Mode. Click on Restart.
- Again, you’ll notice another pop-up window where you can choose if you want to continue opening Firefox in Troubleshoot mode or simply Refresh Firefox. Click on Open.
If you choose Refresh Firefox, your browser will be restored to default settings permanently. This means that any settings you modified, any themes, or extensions will be removed.
