How Do You Remove the Auto-Scroll Icon From Middle-Click?

To begin, open Firefox into the main window, then click Settings > Help > Troubleshooting Information. This will bring up a new screen with a ton of different options listed. Here click Open Folder next to Profile Folder, then double click on the chrome folder in the File Explorer window that appears. 


Inside this folder, you will see a file called userChrome.css. Double-click on this file and it will bring up a notepad file. Copy and paste the following text into the document (below any other text if your document isn’t blank). Once you’ve done this, save the file. 

.autoscroller {

  background-image: none !important;


With the first change out of the way, type about:config into the address bar of Firefox, then use the search bar to search toolkit.legacyUserProfileCustomizations.stylesheets. When you find it make sure set to True (on) if it is appearing as Falseit is disabled. After making this final change, Restart Firefox and you’ll be able to use the middle mouse click auto-scroll feature without seeing the annoying scroll icon.
