Chrome has this handy tool:

clear storage

Lets you purge all kinds of storage for a specific website without ruining your experience for all other websites.

How do I do the same in Firefox?

    I think you go into firefox's 'history' and choose 'forget this site'. But I can't test right now! Sep 14, 2016 at 15:26

(Today) you can find the option you're looking for in the address bar. Just click on the icon beside the shield, it's usually a small lock or a sheet of paper. This opens a small context menu with the option to delete cookies and website data. (Sorry for the German screenshot)

Tested with Firefox 89 Developer Edition.

Screenshot of Firefox with the described context menu open.


Hit F12 to pop open the developer tools menu and go to the Storage tab. You'll be able to view and delete the Cache Storage, Cookies, Indexed DB, Local Storage, and Session Storage for the domain of the page you're currently on.

    how? I'm not able to right click to delete anything. Mar 3, 2020 at 1:51

You can clear the recent history as described at the Mozilla support website.

Firefox has a dialog, which you can open via the Firefox menu button > History > Clear Recent History... or by pressing Ctrl+Shift+Del.

Clear Recent History dialog in Firefox

In there you can select the time range to clear and what items to remove by clicking the arrow button besides Details and then click Clear Now to clear the history.


you can use this extention: https://addons.mozilla.org/en-GB/firefox/addon/clean-guru-cache-cleaner/?src=search (Clear all storage)

  • It doesn't say on the Firefox extension's page whether it can purge all data for a specific website.
