LinLog

I always have to look this up whenever I start with a fresh Firefox config on my main desktop.

In my xorg.conf I have XAxisMapping set to "6 7", which normally allows me to use a button to scroll horizontally. However, in Firefox, this moves back and forth through the brwoser history. Needless to say, this is endlessly annoying.

The quick fix is to open up a tab to about:config and change the following settings:
mousewheel.horizscroll.withnokey.action from 2 to 0
mousewheel.horizscroll.withnokey.numlines from -1 to 1
The first changes the right/left scrollwheel action to scroll by lines and the second makes the line scrolling normal, as opposed to reversed.
