Best extension for all platforms for this functionality! Thank you!

Very useful, and it only accesses what we browse on youtube :)

In my review 6 months ago I mentioned this add-on needed an updated. Well, it's now been a year since this was updated and Youtube has gone through some major design changes since then. Sad really because it had promise.

This addon had some nice features, but probably from a combination of youtube changing too much and the addon getting no updates, there are some wonky functionalities that I don't have the patience to deal with. Too bad, it was a good one for a while

Not been updated nearly in a year. Many features not working.

It doesn't do what I want, while doing a lot of things I don't want that can't be turned off.

There's a lot of promise here, but there's no polish. Some features work great, until you move/resize the screen. Some features don't work the way you'd want them to. No volume controls for the mouse wheel. It will eventually be a contender with "Enhancer for YouTube™" but I'll give it 6 more months in the oven until I try it again.

The only feature I want, block channel, doesn't work for me.

Could you make the custom shortcuts work in another tab or while using PIP? I'd like to use rewind-forward keys from outside Youtube

No update since January 2022.

Youtube has updated her design and the thumbnails won't showing.

Please update this extension.

Installed this just for the "reverse playlist" function. :-D
Lot of other goodies.

字幕が常にオンになるのだが？

For the most part, this extension is amazing, definitely helps with combating YouTube's auto quality setting too.

This extension is missing out on a lot of the updates from its GitHub repo however.

If anyone is coming across an issue where you can't re-enable comment avatars try this:
#1: Go to "about:devtools-toolbox?id=%7B3c6bf0cc-3ae2-42fb-9993-0d33104fdcaf%7D&type=extension"
#2: Click "Storage" from the top if it hasn't been selected already
#3: Open "Extension Storage" from the left side
#4: Click on the first result
#5: Click "Filter Items" and type "hide_author_avatars",
#6: Right click on the first result and click "Delete hide_author_avatars"
This should bring back comment avatars (you may need to reload existing YouTube tabs)
You do need to delete the key since setting the value to "false" doesn't work on this particular version of Improve Youtube (3.935).
