In version 2.0.128 "video codecs and formats" stopped working.

Amazing and extremely useful add-on which truly enhances YouTube. However since the latest update Enhancer often won't show up and boost the volume. Please fix this.

Latest update broke the addon for me!

In the latest version the speed auto-setting started to work strangely. Previously it was enough to set 1x again in playlists and before restarting the browser all playlist videos would have 1x speed. Now, when loading each new video from playlist, the speed is set from the default settings, which is inconvenient: you have to open the settings and reset the values in order to listen to a playlist of music.

The only reason I won't make this a 5, because the "reverse order" button no longer appears on the player even despite me enabling it. If this issue is fixed or troubleshooted, I'll rank it 5 stars.

Hey admin, YouTube has put 'Save' button (Watch Later) below those three columns (•••), I wish that button to be as a standalone next to Thumbs Up/Down, please - then it's 5/5.

Muy bueno, me encanta 👍

this extension is truly amazing for what it does but the most annoying thing about it is the pop-up player that shows up when scrolling, when on fullscreen the scrolling doesn't activate the mini player at all.

I wouldn't want to use YouTube without this extension again, but it's so frustrating that around once a day, parts of it will just stop working. The only way I've found to fix this is to clear cookies both YouTube & Google, and sign in again. This fixes it for another day.

This is a great add-on for firefox. However there are features that can be added and I can't believe they haven't been added years ago. For example, I need an option to check if closed captions are enabled and disable them. Often times I use youtube without being logged in and closed captions are on by default. It's so annoying. Right now I can do this by using a script I found on some website. Also an option to organize comments by number of replies and number of likes would be nice. There is only 1 option to organize comments. Newest to oldest. More options to organize comments would be great. Thanks.

Не изменяется цвет полосы просмотра видео, стал всегда красный.

It would be great if we could get an option for the video controls to open on hover, or at least give us a keyboard shortcut to hide/show it.

I love everything about it apart from the fact that it seems to refuse to work with middle-clicking (open in new tab) videos. That is my preferred way of browsing youtube as there might be more than one interesting video in my recommendations and it is ruined if I change the tab. Please invent a solution for this.

有時候看影片時插件並沒有載入無法使用

There is no setting for it to default to the new quality option of 1080p enhanced bitrate (i have youtube premium) otherwise this extension continues to work fine for years.

Impressive level of control over YouTube. My favorite feature is forcing it to a specific resolution. YouTube lately has been quietly downshifting your video resolutions by default to save themselves bandwidth.

4/5 stars because this doesn't include a feature (That I have found) for quick and easy YouTube downloads. Would be an awesome feature to add.

Please keep support for Firefox ESR version.
