Mircosoft classifies this application as harmful for the Edge web browser, which I personally cannot understand.

Does NOT remove all cookies, e.g., youtube-nocookie.com 64kb remains in Manage Data despitre multiple attempts to clear it.

"Clear Browsing Data" indicates that it has cleared everything multiple times. When I go to Firefox "Settings-Privacy & Security" I still have cookies and storage items from Google (and occasionally other sites) that must be cleared via Firefox settings.

Not working. I tried to remove all data, then open devtools and found cookies, localstorage data and so on

This is a great addon, however if I select IndexedDB data, it takes about 5 minutes to finish and Firefox becomes unresponsive while waiting for it to complete.

Thank you.

Удобная штука!

Would be nice if I could clear cache and browsing history for a specific url. Firebox seems to have a pretty strong caching mechanism for url routes.

This would be super useful for my localhost development

Najlepszy!

This one actually works! I've tried several other similar add-ons, and none of them worked. But this one does.
If it had the option to clear everything when I close Firefox, then I'd give it five stars.
