I found that unlock was able to block many sites and content as well as tracker.
Being able to add more to the list if you choose to do so.
Being able to override many Global or Local Java script filter list to your own desired filters.
I found it to be a powerful and thorough available to all for free.

Ok

Excellent ads blocker. But since today it makes Facebook flickers: ads are flickering on screen instead of being completely hidden. I hope the developer can fix that.

Does not work on Youtube, it's the very same with other users!
Even after updating and clearing cache it doesn't work.
And surely i did purge all cashes but Youtube displaying ad on the bottom-right of their video player.

Is this the end of ublock origin?

Mr.Hill, Can you please fix it.

good

Welp, Youtube are being crybabies again. Seems like they are blocking the whole player now if Ublock is active. Eagerly await Ublocks update so I won't won't be annoyed by youtube's garbo ads. Giving it 4 stars b/c youtube being crybabies isn't your fault. If their ads weren't so damn intrusive we probably wouldn't even need ad-blockers to begin with.

addition/edit: disregard. Just cleared and refreshed the filter list it's working without issue. Thank you for all you do.
