For about 24hr now, every time I clear cookies and cache data, 20kB remain. I clear this data often, and the cookie and cache data always registers "0kB" after I click on "Clear Data", until yesterday. My OS is Ubuntu 22.04. Where can I find that file so I can delete it?

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
