Now I won't have to switch to another browser :D Could you also add support for the ability to switch between browser tabs using the mousewheel? That was my most-often used feature in the previous add-on.
You can change tabs with a wheel gesture. If you mean by scrolling the mouse wheel on the tab strip, then that is not something that is possible to implement anymore. See: https://bugzilla.mozilla.org/show_bug.cgi?id=1285812
