I am using the Addon called Cookie Quick Manager. and it has a feature called 'Delete current site LocalStorage" which is very good. but since new versions of firefox, that feature just vanished? Addon didn't get updates for 5 years, but delete local storage button suddenly disappear. Does anyone have any idea why? I was really liking it. You can see in the addons screenshots that that button existed.

Serves ads.

Does exactly what it says it does and does it well. It is also nicely documented on how to use it effectively without too many words.

cool prog

Very satisfied with the extension, everything works as intended! :)
Plus, it's open source, which is a great bonus.
Thanks to the developer and his contributors for this gem.
