How to Clear Cache and Cookies From Firefox Browser


Firefox is one of the most commonly used web browsers. It offers a variety of add-on features and is handy with extensions. A web browser is a complete system that should be optimized regularly. In this blog, let us understand how to clear cache and cookies from the Mozilla Firefox browser and how it can help you enhance your browsing experience.

Clearing your browser of cache and cookies takes it back to the default browser experience you had when you installed it. This means it removes the saved data like history, offline pages, indexed web pages, etc.

If there are any bugs that you feel are bothering your browsing experiences, like visual issues or slow loading speeds, clearing caches and cookies can help you with that too! Several users never clear their cache, which impacts their browsing and PC performance.

If you use Mozilla Firefox for Windows, there are multiple ways you can uplift your browser experience and clear cache and cookies instantly. What are those ways? Let’s discuss it!

Ways to Clear Cache & Cookies From Firefox Browser

The first one is the traditional and basic way to handle Firefox cookies and caches. There are inbuilt options in the browser for Windows 7 and 8 that help you clear all the components, such as your browsing history, cookies, and cache, all at once. All you have to do is –

  • Click on the three-line hamburger menu on the top right side of the browser.
  • In the drop-down menu, find the Library.
  • Click on the library. It will open a menu with Bookmark, History & Downloads.
  • Click on History and then Select Clear Recent History.
  • Once you click on it, you get a popup asking you about the time range you want to delete.
  • In the Pop-up, you can select a dedicated time frame, cookies, cache, history, etc. Select all of them and from the drop-down menu, select Everything.
  • Click on delete, and you are good to go!

If you are using Mozilla Firefox on Windows 11, the newer version has a dedicated settings menu to delete cookies and cache. Here’s how to utilize those settings.

  • Open Firefox and click on the three-lined hamburger menu icon.
  • Click on Settings.
