Unlike Internet Explorer, Mozilla Firefox is a third-party browser having no integration with Microsoft Windows, and it does not support remote administration by default. Yet there are instruments allowing to remotely configure Firefox like Internet Explorer. I order to use this instruction you will need a freeware package FirefoxADM. It can be downloaded from the repository SourceForge: http://sourceforge.net/projects/firefoxadm
Before proceeding with distribution of proxy settings for Firefox, download and extract the package FirefoxADM on a server with Active Directory.
1. Pushing out Firefox proxy settings with GPO
1.1. Open the relevant GPO for the site, domain or organizational unit in the Group Policy Object
1.2. Expand the following levels within the tree: User Configuration > Windows Settings > ‘Scripts (Logon/Logoff)
1.3. Double-click “Proxy-settings” in the main policy area.
1.4. Click the “Show Files” button; this will display the folder the script will be stored in.
1.5. Copy and paste the script firefox_login.vbs from the FirefoxADM package into the folder.
1.6. Returning to the “Logon” properties window, click “Add”.
1.7. Browse to the location of the start scripts folder where the script was just copied to, select the file and click the “Open” button.
1.8. Click “OK” and then “OK” again to save the changes.
This has now configured the GPO to run a script which will lockdown the Firefox settings when the
machine first starts up. You now need to add and configure the Administrative Templates which will
be used to define the locked down proxy settings.
1.9. Expand the “User Configuration” level in the tree.
1.10. Right-click on ‘Administrative Templates’ and select ‘Add/Remove Templates’.
1.11. Click the ‘Add’ button and browse to the location of the startup template firefoxdefaults.adm, select the file and click “Open”. Click “Close”.
1.12. Expand the “Administrative Templates” level under ‘Computer Configuration’.
1.13. Select “Mozilla Firefox Default Settings” in the tree.
1.14. Double-click “Proxy Settings” in the main policy area.
1.15. Select the radio button “Enabled”.
1.16. At this point you can begin entering the proxy settings that are to be pushed to users; this
information can be found in your provisioning email.
1.17. Once finished click “OK”.
