Status: RESOLVED DUPLICATE of bug 1165286

(Core Graveyard :: Plug-ins, defect)

Description

[Paul]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 2015051400

Steps to reproduce:

1. Firefox 38.0.5 for Windows
2. Set proxy to "use system settings" (or manualy). proxy: myproxyserver:3128
3. Launch java: https://www.java.com/en/download/uninstallapplet.jsp and start "verify java version"
4. If the computer has access to the Internet only through the proxy, we see only gray square.



Actual results:

if the computer has direct access to the Internet, netstat -b says:
 TCP    x.x.x.x:p    myproxyserver:3128           ESTABLISHED
[firefox.exe]
 TCP    x.x.x.x:p1    a23-196-233-73:https   ESTABLISHED
[jp2launcher.exe]
 TCP    x.x.x.x:p2    a23-54-139-27:http     ESTABLISHED
[jp2launcher.exe]
... ...
Thus, firefox goes through a proxy and load applets directly

As a result, firefox 38.0.5 do not work with Java applets page through a proxy

Firefox 37.0.2 does not have this problem, with him netstat -b says:
TCP    x.x.x.x:p    myproxyserver:3128           ESTABLISHED
[firefox.exe]
 TCP    x.x.x.x:p1    myproxyserver:3128   ESTABLISHED
[jp2launcher.exe]
 TCP    x.x.x.x:p2    myproxyserver:3128     ESTABLISHED
[jp2launcher.exe]
