Tab Mix Plus

I just updated to ff3, and its great and all but there's something that's bugging me about the tab scrolling, I haven't found anything about fixing it.

The bar with all the tabs on it scrolls more more then it did on ff2, but for some reason its also scrolling up and down a tiny bit, like when I scroll to the left, before scrolling left it moves down, then to the right it scrolls up before going right. So basically I was wondering if anyone had some info on how I could change it form going up and down, but also is there a way to change it so it doesn't scroll so much? Like in ff2 when scrolling it would go over 1 tab at a time for each click of the mouse wheel.

Here's a pic of it.



I tried changing some increment thing I found but it didn't change anything, and I found some chrome script for changing tab sizes but it just cuts of the bottom of the tabs or makes them longer, still doin the same thing. It does it with the exstentions disabled, with my visual style off and on the default theme, it doesn't do this with tab mix plus installed except when ur on a page you can't scroll, like Google.com, then it does it, it's not all that big of a deal its just gettin annoying to me lol, the little things do that =x.

Thx.
