this week i have noticed that some videos have caused my browser to hang and then i get the notification that this addon has stopped responding.
the browser would hang at that tab until i hit the "close this addon" button, which would resolve the issue but naturally no longer would work on that video.
i have noticed that the issue happens only on videos that the owner had disabled this addon from working.
other videos would work just fine.

sick dizlikes ma boY.!!

Optimize settings for the mobile version with the Firefox nightly android app.

Very amazing extension. Youtube shouldn't have removed the dislike button in the first place :\

Unsure if its a recent issue, but any youtube video i check for dislikes ends up showing the count as "temporarily unavailable". And thats despite it being logged in.

Seems to work fine. Youtube is still retarded for removing the public dislike count.

This is a great addon, but
Especially the video page that pops up every time on the video page and forces you to "subscribe to my channel".
On that particular page, when I manually clicked on a particular video and tried to play it, there was a pattern of it failing to play.

I'm sure there are a number of factors, but I was able to play videos with manual clicks with this add-on disabled, so maybe this add-on is the problem.
