Summary

This document consists of a brief, basic configuration example for Mozilla Firefox 1.5.x. This example contains steps to configure proxy settings globally for any new user running Firefox. Firefox documentation should be reviewed before deploying the product in a production environment. This documentation can be found here: http://www.mozilla.org/projects/firefox/.

Configuring Firefox to Use an HTTP Proxy Server for New Users

Publish Firefox according to the documentation for the version of Citrix MetaFrame or Citrix Presentation Server in use. The default path to the Firefox executable is: C:\Program Files\Mozilla Firefox\firefox.exe.

Firefox mainly uses text files for configuration as opposed to most other Internet browsers such as Internet Explorer which mainly uses the registry. Firefox uses text files as templates for new users who log on and run the application. In this example, the template file used is named all.js and is located in C:\Program Files\Mozilla Firefox\greprefs. This file controls functionality such as default settings for proxy servers, news servers, cookies, and fonts. Once a user logs on and launches the application, the user can then change these default settings which will then take precedence over the defaults specified in the all.js file. These user specific settings are stored in text files in this folder structure:

C:\Documents and Settings\username\Application Data\Mozilla\Firefox\Profiles\randomcharacters.default

Note: The “Application Data” folder is hidden by default.

Proxy settings can be set globally for any user that runs Firefox on the server for the first time by editing the all.js file. For example, below is a section of the all.js file where the name of an HTTP proxy server can be defined and enabled any new user that logs and runs the application:

pref("permissions.default.image", 1); // 1-Accept, 2-Deny, 3-dontAcceptForeign

pref("network.image.warnAboutImages", false);

pref("network.proxy.autoconfig_url", "");

pref("network.proxy.type", 0);

pref("network.proxy.ftp", "");

pref("network.proxy.ftp_port", 0);

pref("network.proxy.gopher", "");

pref("network.proxy.gopher_port", 0);

change this line from this: pref("network.proxy.http", "");

to this: pref("network.proxy.http", "EnterNameOrIPAddressOfYourHTTPProxyServerHere");

pref("network.proxy.http_port", 0);

pref("network.proxy.ssl", "");

pref("network.proxy.ssl_port", 0);

pref("network.proxy.socks", "");

pref("network.proxy.socks_port", 0);

pref("network.proxy.socks_version", 5);

pref("network.proxy.socks_remote_dns", false);

change this line from this: pref("network.proxy.no_proxies_on", "localhost, 127.0.0.1");

to this: pref("network.proxy.no_proxies_on", " ");

and add this line here: pref("network.proxy.type", 1);

pref("network.proxy.failover_timeout", 1800); // 30 minutes

Now when a new user logs on to the server and launches Firefox, the user sees the proxy server information defined within the application GUI. These settings are found by going to Tools > Options, click General, and click the Connection Settings button.
