1130414 - Flash no longer works on Windows XP x64 due to enabling of the no-admin sandbox for Flash

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[[SV Manager] Florin Mezei, QA (:FlorinMezei)]

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?

Actually it doesn't seem to be working at all, as pages do not load with e10s enabled (other than about:xxx pages).

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).

[Robert Kaiser]

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.
