In some scenario’s you want to remove some buttons within the options of Mozilla Firefox. Because there are not that enhanced group policies for Mozilla Firefox, you’ve to script something. In my example I’ve used RES Workspace Manager to distribute the modified files, but you can also use something else. For example: PowerShell, batchfiles or Group Policy Preferences.
You can edit the file userChrome.css in the folder AppData\Roaming\Mozilla\Profiles\<nameofyourprofile>\chrome to tweak the menu settings within Mozilla Firefox. In my example I’ve added the following rule:
/* Remove connection button */
#connectionSettings { display: nome !important; }
When you open Mozilla Firefox the next time, the “Settings” is gone! 🙂
