1195761 - Unity Web Player game is not downloaded with dom.ipc.plugins.asyncInit true

Status: RESOLVED DUPLICATE of bug 1194600

(Core Graveyard :: Plug-ins, defect)

Description

[Petruta Horea [:phorea], Desktop QA]

Reproducible with Firefox 41 beta 2 (20150817163452) under Win 7 64-bit and Mac OS X 10.10.5.
Not reproducible with latest Dev Edition 42.0a2 and Nightly 43.0a1 2015-08-18

Steps to reproduce:
Pref dom.ipc.plugins.asyncInit is set to true by default
1. Install Unity Player - https://unity3d.com/webplayer
2. Open http://www.games.jocuri-unity3d.com/200mph-thunder-road-unity-3d.html
3. Restart the browser and reload the game

Expected results:
The game is downloaded and loaded each time the browser is restarted

Actual results:
After the browser is restarted, the game is not downloaded. The error "Failed to download data file" is shown: http://i.imgur.com/YfDCmAx.png
Setting the pref dom.ipc.plugins.asyncInit to false no longer shows the issue.

Note: This also reproduces with Firefox 40 beta 8 so it's not a recent regression.

I could be wrong but I think this behavior is intentional. See bug 1196000.

Aaron, is this a real issue? Or is this by design based on the fix for above mentioned bug.

Seems like a regression. Tracked.

We should verify that this is fixed in the next 41 beta.

Florin, can your team take a look at that?

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

Yes, we intend to verify all bugs blocking bug 1195607, and close those fixed by bug 1194600. We'll see if we can start today or next week.
