How can I get the middle mouse button to behave correctly in Ubuntu? Clicking the middle button does not show the arrow which allows me to scroll the page by moving the mouse.


  1. Firefox 3.6.8
  2. Mouse: Microsoft Intellimouse Explorer 3.0

Edit ➜ Preferences ➜ Advanced ➜ Check 'Use autoscrolling'

  • Works for me only if smooth scrolling is disabled. – Somebody Dec 17 '13 at 15:06

    Worked for me even with smooth scrolling enabled. Kubuntu 14.10 Firefox 29. Really usefull when using a stylus! – user69112 Jun 17 '14 at 20:00

    Great to know this can be switched off. – Harald Sep 17 '17 at 8:33
  • In about:config this is listed as general.autoScroll - To be set to true to activate. – Fiximan Feb 10 at 14:19

    I've been clicking my middle mouse button like a fool for days trying to scroll. I finally decided to look it up. Why the heck was it disabled on Ubuntu to begin with?! – adjenks Jun 15 at 18:50

Just to precise, since version 57 of Firefox the path is the following: Menu ➜ Preferences ➜ General, then all the way down in the Browsing section check the box Use auto scrolling.
You can also just type auto in the search field once you're in the Preferences window.

See this screenshot:
