 Given it worked before I think it's Youtube fault. On all major platforms
 they have native plugin of either NPAPI and PPAPI flavor. Only niche
 platforms still need nspluginwrapper.
 
 After a bit more testing I've tried to summarize the bug in order to get
 feedback from other BSD and Linux folks

 > In Epiphany YouTube still works.
 
 While Firefox uses IPC code based on Chromium it's now quite modified
 and out of date with upstream. Epiphany (webkit) and Opera probably use
 different implementatios to push plugins out-of-process.
 
 > HTML5 is still too buggy,
 
 Why none are reported? Are you implying 20121010 in UPDATING ?
 Perhaps, not being default and to have a known issue wasn't enough
 discouragement for users to not enable ARIFF_OSS option.
 
 > and not available for all videos,
 
 Try using fullscreen playlist trick:
 
   1/ generate a playlist or use an existing one
   2/ enter fullscreen mode
   3/ move within playlist to the flash-only video (those with ads)
 
 or check userscripts.org.

 It's a bug in OSS backend for libsydneyaudio. But the library is going
 to be removed with Firefox 22, anyway.

 Try to do the same on linux i.e., disable native flash plugin and
 use nspluginwrapper.
 
 >>Fix:

 nspluginwrapper by itself may not provide enough security:
