Works fine with the bars appearing almost instantly. You do have to follow the instructions and jump through all those hoops needed to get a Youtube API key though, otherwise if you use the public "Invidious" key instead then only some of the thumbnails get the bar and only after waiting several seconds.

Pity this addon doesn't use that API key to add a tag to the thumbnails to tell you if they're available in HD or not, because that's the other thing that tells you if the videos are worth watching or not.

Excellent extension that works perfectly. Has clear steps for setting it up with the API key. Thanks for making this and keeping it open source :)

I have used this add-on for a long time. Despite having to follow additional steps, which are very easy, the add-on is a must for watching YouTube videos. I also give 5 stars for the communication of the developer knowing what has to happen for this to continue to work.

Works fine with the new api fix things but it is still annoying that it places itself at the bottom of the thumbnail and moves the playback red bar to the top instead of just placing itself at the top.
Wish there was a setting to reverse them...

Ok, it works now.

Occasionally and unpredictably stops displaying the ratings bars (maybe a YouTube API quota issue per the 0.0.42 release notes?) but this add-on is otherwise very well designed and has no doubt saved me hundreds, if not thousands, of wasted clicks and page loads over the past year or two.

When it works, it works flawlessly. However, sometimes, for no apparent reason, it just stops working for a few hours. Unfortunate, but not necessarily within the developer's control.

It seems really inconsistent as to whether it wants to work or not. Half the time it works fine, half the time it doesn't work at all.

It works, and the essential customization is there. Excellent!
