Wish the damn toolbar could be turned off. I got sick of just hovering my mouse over the speed control and having videos jump to 4x when I don't want it to, so I uninstalled it. Fix this and I'll probably use it again, but for now I cannot recommend this add-on.

No longer working. Please fix.

Closed source.

its not

the addon was so good, but for the past week or so i got issues with video but most usually sound stuttering/distortion, disabling the addon fixed those issues :(
I will try again if there are any updates.

Not sure what I'm doing wrong, everything's up to date, the extension is activated, I'm logged in and everything...but it just won't fire up on YT.
The Chrome extension works flawlessly for me though.

Not working. Hasn't been working for half a year now.

Causes firefox to crash randomly.

Je comptais sur cette extension pour bloquer la lecture automatique qui m'exaspère mais ça ne marche pas.

Abuses user trust by inserting ads in the settings and opening the ad-on settings page *without user interaction*. Unacceptable.

Recommended label needs to be removed.

It is nice that another function has been added for the reinforcement of the volume. However, in the standard output, the volume has been reduced by more than 50% so that the volume function must be forcibly switched on, so that one can even understand something from the video. Furthermore, the sound quality has been deteriorated by this function massive. It is sometimes so that you can not understand the language (the spoken) in some videos.

Further criticism is that if you click full screen, the video is stopped for 1-2 seconds as if it would be reloaded.

There are even more mistakes and bugs, but all listed here would not be possible. As soon as these bugs mentioned above is resolved immediately, there are several stars from me. Otherwise, these addon does not even earn a single star.

I originally really liked this addon as it worked perfectly and added a lot of nice features. However, they main reason I got it was so that I could alter the playback speed of the videos. At first it worked perfectly but now when I try to change the speed instead of evenly moving up a little bit at a time, it zooms ahead as if I spun the wheel like crazy. I can't find any way to alter the speed at a reasonable rate other than to open the settings and change the default speed. Fairly useless to me now.

Confusing main page...

Sorry Enhancer for YouTube™ is a No Go. sponsor ads showing up. Also is it me but the developer is reduced privacy whilst using his app ? I have privacy concerns . What a pity this add on has gone downhill almost over night. I now use a alternative. "improve +++ ++++! "
