After installing Mighty Mouse and using it with Safari, I was greatly pleased with the horizontal scrolling around pages, using the scroll ball. Unfortunately on Firefox, the horizontal scrolling moved me forwards and backwards through my current page history. So left scrolling moved me to the previous page -- in theory. The problem for me, with this behaviour, is that I could not control how many pages forward and backward I would go, and often I would scroll forwards and backwards through pages when all I wanted to do was scroll up and down.
To most it may be obvious on how to fix this behaviour, but for the rest of us, you can easily change the horizontal scroll action in Firefox, so that the scroll ball will scroll you up and down, and left and right.
Simply launch Firefox. Enter about:config as the URL and hit enter. Then scroll down the page until you come to this entry:
mouse.horizscroll.withnokey.action user set integer 2
Change it to read:
mouse.horizscroll.withnokey.action user set integer 1
To do this, simply double click on the 2, and a pop-up window will appear; enter 1 and press Return. The only drawback to this (which I have not yet figured out how to solve) is that when I scroll left and right, the directions are reversed. This is still better for me than scrolling forward and backwards through pages.

I recently got my Mighty Mouse and within thirty minutes, I discovered a major annoyance: horizontal scrolling in Firefox is interpreted as history forward/back. However, I found a solution to this problem on this page. Although this page is related to an alternative scroll pad driver (which adds scrolling capabilities to pre-2005 trackpads, BTW), the Firefox-related settings solved my horizontal scrolling problem with the Mighty Mouse as well.
In Firefox type about:config in the address bar. Change the following settings:
