Reset or Update Firefox

Browsers are often the target of malware. Malicious apps will take a look at a browser. The infections are difficult to get rid of and most users have to uninstall and reinstall the browser to fix the problem. That’s why browsers now have a reset or update feature.

Reset / update vs clean install

Resetting / updating is different from a clean install. It resets all configurations to the default configuration. It also removes all add-ons. It still uses the same profile folder and some of the same configuration files. It is not the same as a clean install and may fail if the browser is too damaged.

Stored information will be deleted even though you can recover it if you have sync in Firefox. You will need to sign in again to your Firefox Account to sync data again. It is worth noting that if the malware comes to your profile, it may return.

How to Reset or Update Firefox

Firefox has a built-in reset / update feature built-in. It offers a simple GUI for browser reset.

  1. Open Firefox.
  2. Click on the hamburger icon at the top right and select Support from the menu.
  3. Select More solution information from the submenu.
  4. On the page that opens, click on Refresh Firefox at the top right corner.
  5. Confirm that you want to update Firefox.
  6. The browser closes and reopens.
  7. When the browser opens, Firefox will be updated.

New profile folder

Firefox will create a new profile folder but the old ones will remain. When you reinstall the browser, the new profile folder will be used. If you have removed the malware from your system, the new profile folder should not be infected again.


If your system or browser has been compromised, you should remove the source of the infection before you begin to repair the damage caused. Once you have removed the infection, run a full system scan to make sure there are no files left from it. They may stop the repair or re-capture the system. If your browser is infected, be sure to check the profile folders it has created.
