The Mozilla Firefox browser offers a built-in reset and refresh button that undo all the settings and customization. It helps in removing the browser extensions and also custom settings. After Firefox reset, the browser will start as a fresh installation, and you need manually configure the settings and install add-ons. However, the bookmarks, passwords, and synced data will remain safe.
While the Chromium-based browsers are reigning supreme in today’s time, Firefox is among the very few names that have managed to carve out its rich fanbase without a hint of Chrome source code.
Based on its Quantum Engine, the browser is known for taking the privacy-centric approach. The likes of Enhanced Tracking Protection, HTTPS-Only Mode, and Firefox Containers have ensured the browser can justify its USP.
However, having such a truckload of features might have its downsides as well. If any of its components aren’t working along the expected lines, it could spell out trouble for the entire browser.
Along the same lines, corrupt or outdated data, malicious third-party scripts, trackers, and issues with any of the installed add-ons could all hurt the overall functionality of the browser.
Fortunately, there’s an easy way out of this scenario. All you need to do is reset the browser, and Mozilla Firefox should be up and running in a fresh new instance, free from all the underlying problems and errors.

It will reset the original Profiles folder in the App Data directory, and all its configuration and settings will be re-generated with default settings. It will preserve your saved website data such as Bookmarks, Browsing history, Passwords, Cookies, and auto-fill information.
