Works great on computer but doesn't function at all on mobile

It just works.

There hasn't been a public API for pulling official numbers for years now. These apps just invent fake numbers based on extrapolations from the tiny minority of people that install the apps, which self-selects for a sad, dislike-obsessed population of people, skewing the numbers more negative than they actually are.

just works, great job!

Youtube is basically useless without this extension

Dont work anymore.

Suddenly stopped working for no reason. Toggling the extension/reinstalling does nothing.

If you are having problems with dislikes not showing, click on the puzzle piece (extension icon) in the upper right which will open a drop down menu, click on Manage Extensions located at the bottom. This will open the add-on extension manager. Lastly, find the Return YouTube Dislike extension and hit the dot toggle turning it off, then on. Return to YouTube and hit refresh. I hope this may help those having issues with the dislikes not appearing. Cheers
