So I bought a new mouse for my iMac today. The Rocketfish Bluetooth Wireless Laser Mouse (model: RF-ABTMSE). Happy with it so far except that it didn’t go back or forward when the scroll wheel was tilted left or right.
So I remembered an alternative mouse driver for OS X I heard about once or twice called SteerMouse. I downloaded the trial version and after configuring the mouse’s Tilt Wheel preference I was able to replace it’s horizontal scroll with moving back and forward instead.
This works with Firefox, safari and I suppose any browser.
