Macintosh, Firefox & Mighty Mouse

Factual Questions
1

I got an Apple Mighty Mouse for Christmas. In most applications, the scroll ball works great. I love being able to scroll sideways as well as up and down.

In Firefox, though, if I have even the slightest movement to the left as I scroll vertically, it jumps back to the previous page in my browsing history. I’ve looked through the Firefox preferences and the Mouse settings in the System preferences and can’t find a way to modify this behavior.

Does anyone know how to fix this?

(I know someone’s going to jump in and tell me to learn to scroll less sloppily, but I have big hands and the Mighty Mouse is tiny. It’s hard to get precise vertical scrolling.)

Better link

As for the question, can’t help yuh. Looks miserable, though – Apple reinventing the wheel, indeed. (I wish Logitech would introduce a Bluetooth Trackman Marble – or even a wireless version with a notebook-scale receiver).

From this page:

  1. In Firefox’s location bar, type about:config.
  2. In the filter box that comes up, type in mousewheel.horizscroll.withnokey.action. Double-click on the entry and change the number to 0.
  3. In the filter box that comes up, type in mousewheel.horizscroll.withnokey.numlines. Double-click on the entry and change the number to 1.

I’m not sure if that works because I don’t have a Mighty Mouse, but try it and see. If it doesn’t work, try changing the 1 in the third step to a -1 instead. If that still doesn’t work, try the other solution (from the linked-to page).

Thank you, thank you! I’ll give that a shot when I get home this evening and let you know if it worked.

Please forgive the slight hijack. Anyone know how to enable middle clicking to open link in new tab in Firefox on Macintosh? Microsoft Optical USB mouse. Intellimouse software allows different button profiles in different applications, but I can’t figure out how to set up the middle click like in WinXP.

If the previous suggestion don’t work, go to your system preferences and look at appearance. If you have “Click in the scroll bar to: Jump to the next page” change it to “jump to here”
I had a similar problem in a different application and that fixed it.

This worked wonderfully! The second change (your step 3) determines the scrolling speed. A “3” worked well for me. A “-1” makes the horizontal scrolling go backward.
