excellent 99.8% workong

In a word: superb.

It blocks YouTube ads too, Good addon.

Fonctionne très bien !

I tried plenty of adblockers and uBlock Origin is by far my favorite.

It is the most powerful adblocker available as well as having extra features that make it extra convenient like the ability to block all Jabascript like NoScript would do or remove tracker scripts from URLs like ClearURLs.

Additionally, uBlock Origin is fully customisable.

The unique downside was that uBlock Origin is not simple enough for newbies to get into. There are many menus that could be condensed, but once you get the hang of it, it becomes a breeze to use to its fullest extent.
