People searching for how to reset the Firefox should understand that basically it makes the browser start over with a new profile while it saves your important personal data like bookmarks, saved passwords, cookies, browsing history, and autofill info. On the other hand, add-ons like extensions and themes, custom search engines, changed preferences, toolbar customizations, and other browser settings will be wiped out. This reset is a great way to fix bugs and increase the speed of the browser while still protecting your basic data.
