Doesn't work on videos opened in new tabs.
EDIT: I don't know what kind of example you want. Just go to youtube and open any video with a wheel click or with right click -> open link in new tab, the annotations won't be disabled.

Doesn't work if video embedded, only on Youtube site. https://i.imgur.com/NuzExyi.jpg

Not working.
Ubuntu user.

Works only in the first tab, when opened in a new tab it doesnt work

It simply works - hassle free.

Doesn't work anymore.

Update :
sorry mybad, addons conflict. It works very well :)

great add-on, works well

Works fine.

At last, the most annoying thing about YouTube is gone forever! Please don't stop developing!

I don't bother signing in to youtube anymore and I don't allow cookies from them either, and that means that every time I watch a video, all the settings go back to default, which puts the annotations back on. They are always annoying and irrelevant and I got sick of having to turn them off repeatedly. This add-on eliminates the annotations and makes watching a youtube video tolerable once again. If you want to get rid of annotations, this is a very simple add-on and it works. A big thank you to the developer.

No matter if on video settings there's "annotations enabled", annoyng annotations don't appear on video!
Kiko, you're a real coder. Chapeau.

Does nothing more, nothing less. Perfect.

Because this Add-on has no options etc. there is not much else to say.

i was first confused by the fact that annotations are still turned on in the options menu, but annotations are effectively removed.

So this is also the only weakness. You cannot turn annotations on and off the usual way (clicking th youtube option gear). Perfect would be, if you can just change the default setting to off.
