I use the latest version which is just downloaded from source.

[huchengtw-moz]

Basically, I had found it broken this morning(in +0800 tz). And I update my source code to latest version. There is a patch on signature decryption from 82 to 88. Some of youtube videos worked, but only this one failed.
