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

Le son est sacadé

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

Works really well and as intended ! It made Youtube videos way smoother

totally fixed stuttering on youtube. even with a gaming PC VP8/VP9 causes issues

Great addon, thanks )

don't work.

Works great.
