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The extension is out of date.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.

Version .128 - the playback speed does not maintain its setting in the same tab - eg. while viewing the "watch later", or a playlist. On the next video, it resets itself back to the default speed in the options, which is not how it worked in version .126.

The default speed should only be used on a new tab/window.


I am giving 1 star to get the dev's attention on this regression.

Sadly it's broken right now...

stopped working

hbhjmbnmn kiuhun

La plupart des problèmes que j'ai avec youtube depuis des mois provenait de cette extension et de ses paramètres par défauts qui changent sans cesse.
Je l'ai désinstallée, ma vie est redevenue plus belle.

When it works, it's great and very useful. Unfortunately, it loads on maaaybe 25% of videos on a good day. The dev seems to have long since given up on fixing this issue.

DOES NOT WORK AT ALL! NO CONTROLS ARE DISPLAYED AND NO SETTINGS DO ANYTHING

I used to use this for blocking ads on youtube and now this feature does not work anymore. 1 star..

Completely nonfunctional, videos all still launch in automatic select mode at 360p when set to 1080p in the extension, but it also just make youtube slow and sometimes not load at all, is it just a scam extension to try to scrape my data? who knows

ça arrête de fonctionner en plein visionnement de vidéos

This addon has basically been abandoned by the dev on firefox due to some vague reasons that have not been expanded upon and this my new rating and new recommendation. Look into Tweaks for Youtube from InzkDev.
