Load about:debugging in Firefox to get started.Set cookie exceptions for extensions in Firefox Keep the deny all setting, but use exceptions to allow extensions that need cookie access to use indexedDB storage to function properly.Allow first party cookies, and clean up cookies regularly or block cookies and storage.Means: if you uninstall and reinstall, or use the extension on multiple systems, it is different.įirefox users have two options to address the issue: Note that the UUID is randomly assigned during installation. Note that the extensions are listed with their internal UUID and not their name.
If you have folders starting with moz-extension in there, you have extensions that use it and thus require cookie access. You can check the storage\default directory of the Firefox profile if extensions use indexedDB. The easiest way to get to the profile folder is to load about:support, and click on the show folder button on the page that opens. While some come with fallbacks built-in to overcome this limitation, it is best to address this head on instead as indexedDB usage is usually the better option to whichever fallback solution is used otherwise. Extensions like uBlock Origin, uMatrix, or Stylus use the storage and thus require cookie permissions even if they don't set cookies to work correctly. These extensions may break if cookies are blocked.
