Here's my test: I install Firefox version of the plugin and enable additional filter lists like "annoyances" and "cookie notices", then go to eurogamer.net

1. I still see cookie notice

2. I open uBlock and it says "blocked on this page: 0"

That's "doesn't work" for me.

Hm, interesting. Did you report this to their bug tracker? They're quite responsive and cases like this help them finding edge cases.

My biggest use-case, youtube, works great, and most other sites work as well.
