FANTABULOUS.

I don´t understand the previous reviews. It still works PERFECTLY on FF 83.0, even when used with Enhancer for Youtube+Thumbnail ratings bar+Blocktube+Toggle youtube playlist, giving me the smoothest Youtube experience ever.

And it makes a MASSIVE difference on my old tablet, which using the extremely underpowerered Intel Atom and a miserable GPU. I just blocked everything but h264 in the addon menu (which reads as AVC1 in the Youtube right click menu) and it allows me to play 1080p videos smoothly, when it used to stutter badly at 720p using the default youtube codecs.

I truly hope you can keep this updated when it´s truly needed, Mr. Developer.

Thanks!
