If you’re having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its default state while saving your essential information like bookmarks, passwords, and open tabs.  All of your Firefox settings and personal information are stored in a profile folder. The refresh feature works by creating a new profile folder for you while saving your important data. Add-ons which are normally stored inside the Firefox profile folder, such as extensions andthemes, will be removed. Add-ons stored in other locations, such as plugins, will not be removed but any modified preferences (such as plugins you have disabled) will be reset. If your default search engine or homepage has been changed, you are having adware or pop-up ads problems with Mozilla Firefox, resetting it can help. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks and open tabs.

  1. Click this Refresh Firefox button directly, if you are viewing this page in Firefox (it won’t work if you are using a different browser). You will also find a Refresh button on the top right corner of the Firefox about:support Troubleshooting Information page.
  2. To continue, click Refresh Firefox in the confirmation window that opens.
  3. Firefox will close to refresh itself. When finished, a window will list your imported information. Click Finish and Firefox will open.
