- Comment: Attempt at clarifying the distinction between what's kept and what's reset by labeling the two lists more clearly on their own lines. Feel free to discard if you don't think this is better. :)

Over time Firefox can develop problems like slowness, crashing, unwanted toolbars and more. Troubleshooting and fixing these issues can be difficult and time consuming. The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
What does the reset feature do?
All of your Firefox settings and personal information are stored in your profile folder. The reset feature works by creating a new profile folder for you while saving your most important data.
Firefox will try to keep the following data:
- Browsing history
- Web form auto-fill information
The following items and settings will be restored or removed:
- Extensions and themes: Although they can be incredibly helpful, some extensions and themes can cause problems. If you need to reinstall important extensions, see Find and install add-ons to add features to Firefox for help.
- Open tabs, windows and tab groups: The reset process will close all open websites. Since your bookmarks and browsing history are saved you should still be able to easily return to your favorite sites. See Where can I find my bookmarks? and Address bar autocomplete in Firefox - Search your bookmarks, history and tabs for more info. Also, since your cookies are saved, you shouldn't be logged out of any websites you were logged in to before the reset.
- Site-specific preferences, search engines, personal dictionary, download history, DOM storage, security certificate settings, security device settings, download actions, plugin MIME types, toolbar customizations and user styles are also not saved. See the Profiles - Where Firefox stores your bookmarks, passwords and other user data article for more information about these.
How do I reset Firefox to its default state?
- 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 on a mobile device.
- You can also find a Refresh Firefox button at the top of the Firefox about:support Troubleshooting 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.
