Rated 3 out of 5 stars

While on youtube.com, after a few clicks on different videos, Firefox will freeze or not responding to mouse clicks.

No freezing if CYS is disabled. Please fix the problem. Thanks.

I am using CYS 5.7.31, Windows 10 Pro 64-bit, Firefox 51.0.1 (64-bit), and ffmpeg-20160116-git-d7c75a5-win64-static.

Tried CYS 5.7.27, still got the same problem.

This review is for a previous version of the add-on (5.7.31). 

You can test v5.7.33 here:
