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.

parfait pour moi

SAME HERE !! --> not worked 100% of the time, sometimes it just vanishes

please fix subtitle timing issue when video is sped up more than 2x.I'm not talking about auto generated subtitles some silent youtube videos have subtitles added by creator when i speed up the video subtitle get out of the sync and stays on screen for some times

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

Could be 5 stars if it worked 100% of the time, sometimes it just vanishes, out of nowhere, but when it comes back it's wonderful, try it.

Support ended by developer. No longer functional.

good add on

I would like the “Automatically select a playback quality” feature to work on google.com, as I often play youtube from thumbnails.

Its good when it works, but after watching 2-3 vids, the addon stops working until i restart firefox again.

Great extension! I would like to see an image sharpness filter if possible.

Everything is cool, just a shame that support for this browser extension has ended (at least that's how I see it 😐). At least, I hope it will be continue. Because without this extension, browsing YouTube is slow and boring.

Very useful, lets you do some basic things YT should just let you do.
