I use this for the loading time, new YouTube is a lot slower, on my older laptop so this extension speeds it up a lot. Its also cool to see this youtube layout again. But holy, it loads instantly for me so if youre looking for responsiveness, it really does the job.

[READ THE EDIT PLEASE!] This add-on is pretty good! Tho there's issues with video playback (At least when disabling the GaiaBar for some reason.) I don't really care sense it makes YouTube quite a bit more usable on my old 10+ year old hardware and now it loads nearly instantly on my second generation Intel i5 CPU, and might also run well even on a Intel Core 2 duo tho I haven't tried that yet.

Been using it for like around 3 days as of writing this, and I absolutely love it!

EDIT: Yea, been using it for about a week, and I've been experiencing a LOT of problems with video playback on YouTube with this extension, a lot of the time, it will play but then just not wanna continue playing anymore? The video player will just NOT wanna respond once like for example I change the video quality being one of the ways that can cause this. it's so bad in fact that I have to disable the extension entirely just to even watch the video without it breaking all of the sudden, for now I'll bring the star rating to 3 out of 5 sadly, but will bring it up to 5 out of 5 again once it's not as buggy anymore. Also just noting that I'm not trying to be rude by the way, I'd still LOVE to use the extension, but there are some issues with it that makes the experience a bit worse for me.

sometimes doesnt play the video and i have to either ctrl + f5 or click the progress bar, but still good nonetheless

Faster than actual YouTube.

my only issue is that most other addons for youtube arent compatible nor work , at least my nyan cat progress bar works so im not that upset
i know its mainly cus of the code n css n everything is different from the current youtube layout , but id love a solution if possible :3

works great! no problems.

love it! however sometimes it just wont let youtube load?
i'lll go to youtube and it'll load for a minute but then it'll just stay on a white screen? reloading and uninstalling then reinstalling the extension didnt work

a really good old youtube layout recreation
for more personalization i recommend startube for tapermonkey (or others)

Great extension! I do see that sometimes errors occur whilst loading videos/video playback, but it's nothing that bothers me much. I really like how well it, well, works! Made YouTube 1000000x faster, no more AI crap, and it seems to place itself instead of the default YouTube stylesheets/appearance, so you don't even see a flicker of modern YouTube while using this extension. To be honest, I thought I reviewed this already!

TL;DR: 12/10, best extension I've ever seen (besides Tampermonkey and uBlock Origin, of course!), keep up the great work! :D

cant play livestreams

cool

Works reasonably well. One big problem is that playlists >200 videos simply dont play properly. Unable to skip after video 200, and when viewing the playlist generally you cant click on one after video 200 and have it show the playlist alongside the video. Also changing settings is a bit clunky but thats ok. Google plus is everywhere and given that it doesnt exist anymore related buttons dont work.

excellen, make a old machine running really great. Thanks
