Who were you talking to? John Schoenick currently owns that bug,
although I don't think he's working on it yet. We've talked about it on
an off.
Full support for windowed Flash on e10s is possible but would be a ton of
work. Flash is on a downward trajectory and it would be a shame to do a ton
of work to support something that may not be relevant for much longer.
The primary reason I know for windowed Flash to be a huge PITA is
because of the deadlock issues caused by attached input queues. I'd love
to force Flash to be windowless and use our fullscreen support instead
of their own windows, because this would fix many of the deadlock issues.
What other issues are you concerned about specifically?
One idea I had is this: suppose, independently of e10s, we make Flash
click-to-play. (I understand this is already a goal, or at least a wish.)
It is neither a goal nor feasible. We did user research into this at the
beginning of the year, and there is enough hidden Flash out on the web
that click to play is just too confusing for the average user.
Having a master plugin process and connecting all the content processes
to seems like a fairly well-understood problem. It's work, and it's not
work I want do until we're sure we're committing to e10s in desktop
Firefox. But I don't think it presents such a technical barrier that we
should attempt to work around it so drastically in the UI.
