Rated 5 out of 5 stars

Great extension, just what I need.

Like his parent extension:
- It allows moving among tabs only with the mouse, but unlike Tab Wheel Scroll with a key combination so you probably are not going to switch accidentally.
- It lacks the small options menu other extensions like roTab or Tab Wheel Scroll have.
- Needs to be updated for new FF versions (you can change maxversion in install.rdf to make it work with later verions, I'm using it on FF 10.0a1 nightly at this moment).
- Only works with the mouse pointer out of the tab bar, so it also keeps the normal scroll whell behavior on hoovering.
- And it's barely 3KB!

This review is for a previous version of the add-on (0.0.7).
