Pretty nice addon, works fine for me. Classic YouTube performs much better on Firefox, I hate the redesign.

If this doesn't work for some people, YouTube Classic can still be restored using Greasemonkey and a custom script. There's a video tutorial on YouTube. Do a search and you'll find the guy who made it possible. You'll know you've found the right one if the guy starts off by saying those who don't like his videos are free to leave. The workaround is completely legit and is a guaranteed fix if you follow the instructions. I use Gridtube in conjunction with the hack to restore the layout like you see here in the screenshots for this addon. I sought the patch because YouTube Plus isn't compatible with the new YouTube GUI, but it works fine with this workaround. I haven't used this new addon, but it's probably something similar to the hack of which I'm speaking - just automated.

This solved my issues with YouTube lagging Firefox constantly for a few months HOWEVER that is no longer the case. Update needed or is Chrome the only way? I want to keep my rating at 5*s but I'll lower it if nothing changes. :(

Amazing. Youtube loaded way faster. No configuration at all.

usefull

Brings back the faster YouTube experience to Firefox! A must-have Firefox add-on

GOOD add-on but now this add on is dead :( ..
fuck youtube loading shit

It seems that this add-on doesn't work properly now. When I open youtube today, the layout is collapsed.

Sigh!!! :( sadly it seems as though they did something to the classic layout on YouTube's end, now when this extension is enabled or setting the cookie PREF for the classic layout, the video player doesn't display properly. I guess this is how Google plans on forcing people to use the new awful layout, which means YouTube will be slow on every browser except Chrome.
