Firefox's style or appearance can be modified by creating a custom style rule to override the default styles in Firefox.

Custom style rules might not work every time because of other factors (e.g. compatibility with other custom style rules) beyond the Mozilla community's control. Your custom style rule might also stop working each time a new Firefox release comes out.
The following "moving tabs below the URL bar" procedure only works on Linux and Windows. It does not work on Mac OS X.

Here's how to do it:

  1. Create a userChrome.css file following the steps below, or see our community member's video (starts at 8:45). The rules you put in this file will override the default styles in Firefox.
    • Open your currently active profile folder: Type in about:profiles in the address bar, then click Open Folder (Windows) or Show in Finder (Mac).
    • Create a new folder named chrome.
    • Create a desktop shortcut to the chrome folder for easier future access.
    • Make sure Windows is set to show you file extensions like .txt and .css.
    • Create a new text file inside the chrome folder named userChrome.css.
  2. Paste the CSS rules found in the third example here into the userChrome.css file and save your changes.
  3. Reopen Firefox.

(Tip: Turn on your title bar or menu bar after you've made these changes.)
