How to Reset Firefox Instantly -Solve and fix A Lot OF Problems

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:

• Bookmarks
• Browsing history
• Passwords
• Cookies
• Web form auto-fill information
• Personal dictionary

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.
• 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.
• Site-specific preferences, search engines, download history, DOM storage, security certificate settings, security device settings, download actions, plugin MIME types, toolbar customizations and user styles are also not saved.
• All Firefox Services, including Facebook Messenger for Firefox will be removed.

Note: After the reset is finished, your old Firefox profile information will be placed on your desktop in a folder named "Old Firefox Data." If the reset didn't fix your problem you can restore some of the information not saved by copying files to the new profile that was created.
