Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[Ed]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0
Build ID: 20120509070325

Steps to reproduce:

Browsed to netflix.com normally then through vpn. Tried reloading FF, deleting profile & creating new. Tested netflix through vpn in IE, works fine. Sent crash reports.

I didn't bother browsing in safe mode, as Silverlight would be disabled.


Actual results:

browsed to netflix normally, silverlight loads fine and plays. Browsed to netflix using a PP2P vpn configured through windows 7, silverlight crashes 100% of the time


Expected results:

Silverlight should have loaded and started to play media

Safe mode doesn't disable plugins. It only disables extensions and themes.

Can you provide the crash ID from about:crashes?

Uninstalled Silverlight and installed previous version. It still crashed. Installed most recent silverlight from microsoft downloads, it now hangs at 98% instead of crashing. I let it sit overnight to see if it made any progress, but no. Still 98%, after ~8h

Hard to imagine offhand a way for proxy settings to affect rendering through D3D, but I guess anything is possible!

it's a problem to do with pp2p - openvpn silverlight works fine

[Ed]

actually, FF crashed just after I wrote that. It actually crashes FF not just silverlight when in openvpn
