I want to find out where are firefox cookies getting stored in Linux. there is a similar old question here which says that the cookies are stored at ~.mozilla/firefox/<profile name>/cookies.sqlite but i think this is not true anymore because i remove this file but i still have cookies in firefox itself. also i tested the entire ~.mozilla/firefox folder with inotifywait using the following command:

$ inotifywait -mr .mozilla/firefox -e open -e access -e modify

and got nothing!. not even an access event occur when i open firefox and search or open any sites.

  • Have you checked the cache file? Firefox cache is kept under ~/.mozilla/firefox/*.default/Cache.

  • What happens when you nuke your ~/.cache/mozilla/firefox/<profile> folder?

  • Have you actually exited Firefox? If you haven't the file is still open and Firefox is using it. ~/.mozilla/firefox/<profile name>/cookies.sqlite is the correct location unless you're using snap/flatpak. Jun 9 at 11:54
  • thank you all. it was snap and the path is ~/snap/firefox/common/.mozilla/firefox thank you @ams

If you want to know what path firefox is using for your current profile you can check this with about:profiles or about:support in the url bar.

In recent versions of Firefox, the cookie storage location in Linux has been changed.

The cookies now stored in a format called cookies.sqlite within the Firefox profile directory.


YOURPROFILE, if you are using more then one profile, otherwise it's something with default.

If using snap you will find the cookie file in ~/snap/firefox/common/.mozilla.

Check this too, for experimental technology:

There are other storage mechanisms for cookies in recent versions, such as IndexedDB and the HTTP cookies storage API. Check the Browser compatibility table carefully before using this in production.
