Any browser is prone to slowing down after using for a certain time. The performance deterioration can be attributed to the presence of too many temporary files, add-ons, browser corruption, compatibility problems etc. A simple solution to most of these problems is simply resetting Firefox to original manufacturer settings. This should be done once in a week or fortnight depending on how frequently the Firefox browser is used.

How to Reset Firefox to defaults

  1. Open Firefox browser
  2. Type about:support inside the address bar. This will open a page which is related to Firefox troubleshooting information.
  3. Click on Refresh Firefox under the heading Give Firefox a tune-up. Once the option is clicked, it will automatically close the Firefox browser, remove extensions, change the settings to default. It also removes history and favorites, but retain it once the reset is complete.

Try Safe Mode

  1. Once you are in the location about:support, you may also Try Safe Mode if you suspect a problem with Add-on.
  2. Under Try Safe Mode, click on Restart with Add-ons Disabled. If the browser works fine in Safe Mode with Add-on disabled, there is a problem with Add-on. Uninstall recently installed Add-on or recently updated Add-on which is most likely the source of the problem.
