Doesn't seem to be working any more?... I just turned it on, restarted Firefox, and checked stats on a YT video, still says vp09

Expected it to force 4k video to use h.264, but it just completely blocks it instead. Should've been made clear in description. The add-on only allows up to 1080p after installing.

It does block VP9 but I didn't notice a change in CPU usage...

Took the CPU usage on youtube from 8-12% to 2-5% on a 5 year-old gaming PC. It really does wonders.
