The Refresh Firefox feature can fix many issues by restoring your Firefox profile to its default state while saving your essential information.
Note: When you refresh Firefox, your bookmarks, browsing history, open tabs, windows, passwords, cookies and web form auto-fill information will be saved. However, your extensions and themes will be removed and your preferences will be reset. Learn more.
- Click this Refresh Firefox button directly, if you are viewing this page in Firefox. This won't work if you are using a different browser or a mobile device.
- You can also find a Refresh Firefox button at the top of the Firefox about:supportTroubleshooting Information page.
- To continue, click in the confirmation window that opens.
- Firefox will close to refresh itself. When finished, a window will list your imported information. Click and Firefox will open.
Note: There's a Refresh Firefox button in the Firefox Safe Mode window, if you can't start Firefox normally. You can also do a manual refresh by creating a new profile and transferring your important data to the new profile.
Sometimes files in your Firefox profile folder that correspond to the essential information that a Firefox Refresh doesn't remove (such as bookmarks and browsing history) may be causing the issue. You can create a new, additional profile which will not contain any of your old Firefox data. See the Profile Manager - Create, remove, or switch Firefox profiles article for instructions.
If you've tried all of these troubleshooting methods and you're still having problems, here are some other solutions you can try:
Check browser internals
The Firefox Task Manager (about:performance page) lets you see what tabs or extensions are slowing down Firefox. Telemetry Data shared with Mozilla (about:telemetry page) contains detailed data about performance, hardware, usage and customization. The Troubleshooting Information page (about:support page) includes other about: page links and troubleshooting resources. (For a list of all about: pages, enter about:about in the address bar.)
Troubleshoot the Flash plugin
See Flash Plugin - Keep it up to date and troubleshoot problems.
Check for conflicts with your Internet security software
Some Internet security software (including antivirus, antispyware, and firewall programs) can cause problems with Firefox including blocking it from opening websites, crashes, and more. Often you can open the program's settings, remove Firefox from its list of allowed or trusted programs and it will be re-detected and things should start working again. If your program is listed at the Configure firewalls so that Firefox can access the Internet article, you can get specific instructions for how to properly reconfigure it.
Check for malware
Malware (short for 'malicious software') can cause problems with Firefox. Periodically, you should scan your system for viruses, spyware, or other malware. For more information, see Troubleshoot Firefox issues caused by malware.
