I never knew I didn't want warped scrollbars.

I finally put my finger on the change to vertical scrollbars in Ubuntu that I wasn't expecting.

It's described at this stackexchange post and also on a Mozilla page. I'm giving the settings.ini option a go.

Not that I don't think the 'warp' idea is a bad one. But they should've put it on the right click by default, I feel.. not the left.
