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.

Simple, convenient and effective.

Deletes site data of all websites including history. This option should not be default or at-least there should be warning. I'm now using "Cookie Quick Manager" which allows choosing which ones to delete.

This system is already have Firefox browser. But it's save time.
