Reproducible with: - Firefox 36 Beta 7 - BuildID: 20150205114429 - latest Firefox 37 Aurora - BuildID: 20150205004014 - latest Firefox 38 Nightly - BuildID: 20150205030205 Reproducible on: Windows XP x64 NOT reproducible on: Windows XP x86, Vista x64, 7 x64 Steps to reproduce: 1. Open Firefox with a clean profile and load some Flash content (e.g. Youtube Flash video, games like http://www.flashgames247.com/game/flash-sports-games/jungle-ride.html). Expected results: Flash content loads and works correctly. Actual results: - Firefox 36 - Flash content does not load - Firefox 37 & 38 - Firefox hangs while loading the content Notes: - disabling "dom.ipc.plugins.sandbox.flash" will fix this, so this must be a regression from bug 1125891 (which entered Firefox 36 Beta 5) - Windows XP x64 seems to be the only version affected
Forgot to mention that this was reproduced on two separate machines, so I believe this issue will affect all Windows XP x64 users.
I wonder if this is a general sandbox problem on WinXP x64. We had problems on Vista x64 before and I had problems getting the necessary service pack installed on a WinXP x64 VBox, to test it. Looks like I'll need to get back to that. Does e10s seem to work OK on Fx 38?

Thanks Florin ... I think. :-) We can probably safely bet that GMP processes aren't working in non-e10s as well. I'll try and look into this in the next few days.
Note that this affects Firefox 36 Beta 7, so at release (in about 2 weeks) this could mean no Flash for Win XP x64 users (not sure how many there are).
From all I understand, we are not shipping the sandbox for Flash in 36, so at least it should not be an issue for this release. Still important for e10s and if we ship a sandbox for plugins.
So marking to tracking per Comment 6
Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
