1129404 - Firefox 35.0 does not use Proxy settings with flash

Status: VERIFIED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Markus Kopp]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20150108202552

Steps to reproduce:

Since Firefox 35.0 the proxy settings of Firefox are not used by the flash Plugin.
To reproduce: Use a Proxy, do not allow direct Connections to Internet, try to view a Web Video, for example on http://www.handelsblatt.com/video/
Operating System is Windows 7.


Actual results:

The Flash player can not connect to the Internet. You see the Message VE_FMS_CONNECT_FAILED in Flash player. I can see how the flash process tries to connect without using the proxy.
When setting dom.ipc.plugins.flash.disable-protected-mode to true the proxy settings are used in Flash. With this setting proxy Authentication fails very often and proxy Password has to be entered several times when setting the preference.
I have seen this on several maschines and different Websites since Firefox 35.0.


Expected results:

Playing the Video.

If i look at the running Processes the plugin container ist running all the time. The Flash player plugin also. The first video is displayed (Commercial). The second video is not loaded (FME Connect Failed).
