I need help resizing my Minimize and Maximize buttons when in Full Screen mode. They are almost too small to see!

When in Full Screen mode on Mozilla Firefox, the Minimize, Maximize, and Close buttons are extremely small. How do I change the size of these buttons?

Add code to userChrome.css below the default @namespace line.

The customization files userChrome.css (interface) and userContent.css (websites) are located in the chrome folder in the user profile folder.

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Open Containing Folder 
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
