The userChrome.css file in Firefox Quantum still allows for a lot of customization. This file can be modified to hide unwanted menu items, move the tab bar below the navigation toolbar, show multiple lines in the bookmarks toolbar, and do other things that wouldn’t be possible other.

How to do

The userChrome.css file does not exist by default, so once you have a setting or two you want to try, you must first create the file in the appropriate location in your Firefox profile folder.

  • To open your Firefox profile folder, click menu > Help > Troubleshooting Information in Firefox.
  • Click the “Open Folder” button to the right of the profile folder to open it. (On macOS or Linux, you’ll see a “Show in Finder” or “Open Directory” button instead. The following instructions show the process on Windows, but it’s basically the same on Mac and Linux – you’ll just use another file manager and text editor).
  • If you see a folder named “chrome” in the profile folder that appears, double-click it. However, this probably won’t be the case, as this folder is not created by modern versions of Firefox.
  • To create the folder, right-click in the right pane and select New > Folder. Name it “chrome”, hit enter, then double-click it.

You will need to tell Windows to show you the file extensions, if it hasn’t already. Windows hides file extensions by default to make things easier. This step is not necessary on macOS or Linux, which display this information by default.

  • In Windows 8 or 10, you can simply click on the “View” tab of the ribbon and check the “File name extensions” box to make them visible. In Windows 7, click Organize > Folder and search options, click the “View” tab and uncheck “Hide extensions for known file types”.
  • Now you will create the userChrome.css file, which is actually just an empty text file with the .css extension instead of the .txt extension.
  • To do this, right-click on the panel on the right here and select New > Text Document. Name it “userChrome.css” making sure to remove the .txt file extension.

Windows will warn you that it is changing the file extension and this can be a problem for some file types. Click “Yes” to confirm your change.

  • On macOS or Linux, create an empty text file with the same name.
