Firefox is sluggish when watching videos on bilibili.com with live commenting

I'm trying to switch from opera to Firefox, as title says, Firefox is slow when live commenting is enabled on bilibili.com when watching videos, it gets worse if you play video in full-screen mode, and CPU is about 15% higher than opera even not in full-screen.

I've tested on other two similar website: douyu.com and huya.com , turns out the issue is only with bilibili.com, I found that the live comment feature is implemented by canvas on bilibili.com while the other two sites uses css3 instead, and I simply tested canvas benchmark with benchmark1 and benchmark2 and the result conforms my guess -- opera performs much better than Firefox.

I've tried toggle hardware acceleration and safe mode, no significant improvement observed
