It's not just in private mode. Since... Few months (?) ago is not working animore, both in Chrome and in Firefox; private or not. The site isn't blocked at all and still appears complete instead the gray-background message of the extension informing about blocked site.
Anybody with the same issue or knows how to fix it or why it happens? I like so much this add-on and don't want to search another one...

I guess that needs an update since last is from later 2024 and some of you said about same issue since navigators' updates. Thanks and sorry for my english.

EDIT: I don't know why last updated appeared from 2024. I readed again the last reviews and see it was indeed updated again few time ago, when started failing. I searched updates, applied it and now works again like before. Thanks a lot.
