I use my trackpad with touchegg and touchegg-gce for easier configuration. In the initial configuration there's an 'application' section for Chromium navigation which uses 2-finger drag that doesn't seem to work in Chromium or in Firefox (when I add Firefox).
The problem seems to be that the 2-finger drag is used for scrolling left and right. I have the feeling that an override for this function in Chromium or Firefox doesn't work and scrolling is "more important" than forward or back navigation.
With an iMac I saw that this is possible so did anyone get the trackpad to be usable for browser navigation?
