[Mozilla Enterprise] Proxy Settings switch back to "Use System Proxy Settings" on restart

Fri Jul 27 10:15:25 UTC 2018

Hi Mike,

sorry for late answer:

Yes in the Autoconfig file we also set the same as in the Policy:
// Use System Proxy
pref("network.proxy.type", 5)

That was the problem, I changed to defaultPred and now it is working.

Sorry for confusion.

Wish you all a nice weekend!

Freundliche Grüße / Best regards,
Peter Schlierf

Is there any setting related to this in the Autoconfig file?

All the policy does is set the default value. It would never undo a user choice unless locked.

No we do Not use a Distribution.ini, we use in Addition to the Group policy Mozilla.cfg file from autoconfig.cfg.

Two questions:

- What is the change that the user made?   (i.e. to which value are they switching to?)

- Are you also using a distribution.ini file?

No it is not bold,  it is back to Standard and on 5 on next restart.

But from my understanding, if I set in the Policy
Don't allow proxy settings to be changed.

Disabled

It will not become a lockpreference and the user should be able to switch the setting.
Or will the Group Policy always overwrite every setting, although it is not makred as lockPrefernce?

After the policy is set back to 5, is it bold (meaning it's a user set preference)?

The policy code only sets default preference and locked preferences, it does not set user preferences.

So it won't ever cause a preference to be bold in about:config. If it's bold, it means the user changed it.

Hello Enterprise-Group,

hope some of you can help me here, as I could till now not find the reason, why that happens.

We use now the Group Policy feature with FF 60.1 ESR and set the Proxy Settings to “Use System Proxy settings”:
<image001.png>

We explicitly Disabled the feature
Don't allow proxy settings to be changed.

Disabled

But we unfortunately got feedback from some  users where the users changed their settings, but on the next start of Firefox the setting is back to “Use system proxy settings”.

Interesting is after the change in the GUI for the proxy I can see the change in the about:config for this session:
[cid:image002.png at 01D41F45.344DB7A0]
But as said on next start the setting for network.proxy.type is set back to 5.
The other changes stay as value for network.proxy.autoconfig_url is still available.

Anyone else observes this problem or has an idea what could trigger that?
