Upgrading to Firefox 3.6.6 overwrites existing proxy settings
I am deploying Firefox 3.6.6 (as an upgrade from 3.0.4) to hundreds of workstations to run alongside IE, some workstations (with Firefox already installed) have proxy settings set others have the "no proxy server" option enabled.
Whilst testing the silent install (and using the setup.INI file) i notice that once Firefox 3.6.6 is installed it imports the proxy settings from IE ("Use system proxy settings" is enabled!!!) which i dont want. I would like it to upgrade the Firefox software but keep the exisitng proxy settings.
Any ideas? Thanks
This happened
Every time Firefox opened

Sorry, I can't tell you you how to fix that specifically on a mass deployment, but I have seen mention that Firefox 3.6.4-up changed the default setting for this preference to a value of 5, to use system proxy settings. (previous default was 0 - direct connection, no proxy) http://kb.mozillazine.org/Network.proxy.type
In Firefox 3.6.4 the default connection settings have been changed to "Use the system proxy settings".
See Bug 500983 – "Use System Proxy Settings" should be default for new profiles.
A possible solution is to place a file user.js in the default template folder (C:\Program Files\Mozilla Firefox\defaults\profile\) for new profiles user_pref("network.proxy.type", 0);
Or place a file local-settings.js in C:\Program Files\Mozilla Firefox\defaults\pref with this line: pref("network.proxy.type", 0); ..... You can also use a mozilla.cfg file to set the default of the pref defaultPref("network.proxy.type", 0); // set new default value pref("network.proxy.type", 0); // set pref, but allow changes
