It's great at increasing the video size... When it works. When it doesn't, there's no button to press that will make it realize it didn't work.

Sometimes it works and sometimes it doesn't. Not sure why. Does anyone know of a good alternative?

Really good extension except scrolling to the comments is buggy and also using youtube iframes doesn't work with the extension.

Salut, je trouve pas mal cette extension

It's very nice but it makes youtube lag like crazy. I dont like using youtube without this but it lags to the point where if I close the window the video continues to play for a good few seconds after closing.

Its pretty good, and i like its features a lot, but unfortunately i have encountered bugs.

Most notably, the icon bar/buttons under the video seems to just.. disappear. Refreshing the page will not fix it. I noticed that disabling the extension, then refreshing the video page, then enabling the extension makes the icon bar re-appear. But refreshing the page again makes the bar disappear again! Its very annoying and very inconsistent, and it has been happening for a long time.

While the features this addon provides are very nice the simple fact that it never works on links opened from bookmarks means its worthless for a good chunk of my usage and so 3/5.

YouTube playback speed resets after each video, even with the Override default playback speeds option enabled.

In version 2.0.128 "video codecs and formats" stopped working. I installed 126 and it works there.

There is a conflict with this extension and SponsorBlock.
I've reverted to an older version of this extension just so SponsorBlock works again.

As mentioned in a below review, Enhancer currently breaks Sponsorblock. You have to revert to version 2.0.126.1 to fix the issue. For anyone trying to do that, here's how: on the addons page (here) scroll down to "More information" and press "see all versions" to get access to previous versions, then select version 2.0.126.1 and install.

The latest 2.0.128 update seems to conflict with SponsorBlock as the latter no longer skips skippable segments in videos when 2.0.128 is installed. I installed the previous 2.0.126.1 and this fixed it.

Latest update broke the addon for me and I had to reinstall it.

Version 2.0.128 does seem to not work properly still. Ads happen, also some of the features are missing too. for ex: no extra buttons and player does not go full cinema mode etc.

doesn't force the theater mode

When the aspect ratio of the video doesn't match the aspect ratio of the screen, the thumbnail is visible through the gaps in the fullscreen mode.

The color customization, volume boost, and speed controls are my favorite features. The customizable control bar thing is great, but it doesn't show up on live videos, playlists, or any video playing in the mini player as I'm scrolling the homepage. This app could be amazing but it needs improvements.

A great app, some problems, not sure where to send the info, so ...`here` i guess, `stop autoplay` has a pretty spotty reliability, sometimes it stops them, often though, it doesnt, the youtube uploader has set auto play orsomething (maybe its youtube that does it, or recommends it ... ?), whatever the cause, `stop auto play` is usually non-functional. Overall, a great app, again, finding where to report a problem led me to here, so ..here it is. Be good :)

the youtube logo doesn't change color

Toolbar doesn't load 99% of the time, but when it does it works great. Make the Toolbar always show up like I assume it is supposed to and its 5 stars.

Doesn’t work when using a VPN / proxy server, be it a browser extension or a system VPN app.
