2026-06-02	Ru*****	This is a pretty good extension. However, I have had issues where firefox loses all network connection if loading pages with a lot of media, or scrubbing youtube videos fast. I now, after at least a year tried disabling the malwarebytes extension and that fixed the issue i was having. Hopefully this is something you can solve in future updates.

2026-05-22	Gi*****	Broken cookie banners on multiple sites. I wanted to report that this extension causes cookie banners to malfunction on various websites. The banners disappear after just a few seconds, without giving users enough time to manage their consent. I am experiencing this major issue also on my own WordPress site, which uses the Cookie Complianz plugin. Since these banners are configured to automatically reject cookies when closed (keeping them disabled until explicit user consent), certain website functionalities break entirely. The only workaround is to disable the extension's ad/tracker protection, which the vast majority of users obviously won't do. Instead, users just continue browsing without paying attention to the quick disappearance of the banner, completely unaware that the extension has rejected cookies on their behalf and locked them out of some site features.
