If you are using strict mode, it is a known bug. On GitHub, I explained that the bug is due to the new cross-site cookie isolation introduced in 86. This is enabled if you use strict mode or set it in custom. This is a bug in Firefox Webextension API itself and it is out of our control.
Localization are handled by the community here: https://crowdin.com/project/cookie-autodelete. Feel free to contribute there. As for the other item, please open a support issue through our github repository here here: https://github.com/Cookie-AutoDelete/Cookie-AutoDelete/issues/new/choose
A good idea botched by the fact that it doesn't work properly - indexeddb from several sites is not being deleted, only regular cookies are.
In fact, if you enable the IndexedDB option in settings, it will do much worse than that - cookies will pop up from every site visited, effectively doing the opposite of what it's supposed to do. Beware, users!
Crap. I'd like to see all cookies, but this addon shows only domain (doesn't show cookies) of one site which i'm watching. This addon would be much better if it showed all cookies (not only domains) of all visited sites after last clearing.
I'm sick and tired of whitelisting Youtube/google/Steam etc etc, only to have to effing sign in EVERY damn time ! I'd sooner have a bazillion tracking cookies than have to login to ever website every time because this extension no longer works.
