I have an Apple Mighty Mouse, but it's been banged up a bit. The side buttons (4th buttons) are way too easily pressed. When I'm using Firefox, the 4th button can accidentally click and I'd go back one page, which can be really aggravating. How can I disable the 4th button (on either Firefox or Ubuntu) without getting any new hardware?

You could also assign the key to a null command. See askubuntu.com/a/308969/8844 –  belacqua Jul 1 '13 at 22:38

its simple. just follow these steps:

  1. Go into system settings found in your dock or by searching after pressing Alt-F2
  2. Go into "mouse and touchpad" (or something similar, thats just what it says for me)
  3. Go change the setting you want

When posting an answer it's always good practice to go through the steps your posting, so you can verify it works! If you had done so you'd see there is no option in Mouse and Touchpad settings for changing the function of extra mouse buttons. –  Merri Jul 1 '13 at 23:16
i did, i havent done it with his/her specific model, but it did in fact work –  Eleuin Jul 1 '13 at 23:18
Ah, sorry! I realise now that as I'm using a laptop it only gives me touchpad specific options which don't include any settings for extra buttons. :) –  Merri Jul 1 '13 at 23:38
