992880 - Unable to change proxy settings via GUI

Status: RESOLVED DUPLICATE of bug 991461

(Firefox :: Untriaged, defect)

Description

[Tomasz Lipski]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140405030204

Steps to reproduce:

Go to preferences - Advanced - Network - Connection Settings.
Proxy is set to "use system proxy settings" by default.
Change to whatever other option.
Click OK.
Enter Connection Settings again.


Actual results:

The configuration reverts to "use system proxy settings".
Every time.


Expected results:

The chosen option should be enabled instead of default "use system proxy settings".

The only way I can make changes stick is through about:config entries.
Tested on both x86 and x64 versions on Windows 7 x64. Builds v30 and v31.

Everything is working as expected in stable version (28.0).

I understand that it may not be a bug but a feature with some logic behind it but I was not able to find any information on this subject...

Hello Tomasz,

I have tried to replicate your problem, but have been unable to do so... everything reguarding the connection settings seems to be working...

I'm using Windows 7 x64, and my Mozilla is build v31

OK, I dug a little bit more and I have found out that this problem can be observed only when the preferences are edited "in content" (browser.preferences.inContent = true).
If I set it back to false and use the regular menu Tools -> Options and edit the preferences in the dialog window, the changes stick.

Are you using the in-content preferences in Firefox 31? (ie, they show up in a browser tab rather than as a separate window?)

Egh, somehow I missed comment #2, sorry.
