Comment:

 Alright, I think I have figured out all the pieces involved. The problems
 starts with https://bugzilla.mozilla.org/show_bug.cgi?id=1321528 begin
 fixed with https://hg.mozilla.org/releases/mozilla-beta/rev/1c4863a4ff98
 AND NoScript 2.9.5.2rc3 (commit 9eab569b1d443456325e2b253f2cca65eb453c30
 in the git repo at https://github.com/avian2/noscript). The whole
 suspend/resume mechanism got introduced to fix the mediasource blocking
 for us. ;)

 While I don't have assembled all of the pieces to a coherent picture yet,
 the proposed attached fix seems to be a good idea to me. mcs/brade: That
 one works across different platforms, right? If so, do you think you want
 to propose that one for review?
