very often this thing doesn't start. you need to enable/disable the addon and reload the page several times

Doesnt work in new tabs....youtube will "grey out" for a bit.....then load video and this addon will not work. Looks like the developer abandoned this.....Oh well I will use 3 seperate addons to get this functionality back.

The addon will appear here for a short time, until the developer's next tantrum. I advise you to look for alternatives, there are addons much better than enhancer. For example, Tweaks for YouTube.

Great experience in the past. Haven't been updated in a while (or if it ever will)

Support ended by developer. No longer functional.

Addon is broken again. You have to double stretch to get cinema mode to work.

As they succumbed to Google's ressure to stop blocking ads, makes this kinda pointless. go elsewhere for that.

the automatic video stretching function to full screen stopped working, also the top panel with search became separate, when opening each video you have to go to the extension settings again and click the checkbox, and then scroll so that the video is fully visible and the top panel is not visible
ps fix this please and i'll return all of the 5 stars)

Causes music audio on some YouTube videos to become mute.

Was working really well for a long time, but recently it has been extremely buggy and causes YouTube to lag. Videos tend to stutter, the expand video player option doesn't work, the play speed is useless (because of stutter), and in general a lot of the features are currently broken or cause more issues than its worth. I love the extension, but I'm going to disable or uninstall for a while and wait for it to be fixed.

Funcionava melhor no passado.

Edit: On FF This just abandonware at this point, should be removed from the recommended list.

You can use AI to make simple scripts to gain most of the functionality this brings.

The extension is out of date. It causes youtube to be extremely laggy now. Even pausing can take several seconds.

Disabling autoplay no longer works, which was the only reason I installed this extension. Uninstalling now. Pity.

Add-on is no longer working in Firefox and the developer complains that he will no longer fix it because of Firefox policy.

Plugin doesn't work. No bar under the video, no boost option... chrome work, but not in firefox

I used to use this plugin to play my videos at specific speed without it changing back to 1x. But now after some dumb update it stopped doing it. Atleast add an option to override or remove it without removing speeds that are higher than 2x. My disappointment is immesuarable and my day is ruined.

Abandonware for Firefox.

YouTube streams are busted as others have said and either stutter like crazy or often end the stream prematurely while it's still going. Chat still works no matter what but the actual video itself no matter who the streamer is extremely unreliable and is fixed instantly by turning off the extension. Please fix as base YouTube sucks without this extension.

This needs an update. More than half the time it just doesn't work anymore.
