Rated 5 out of 5 stars

Great addon although I only use it to place new tab next to current and to focus on last active tab. Of course v10 (addon friendly firefox) breaks it, even with compatibility check disabled it breaks address bar. You'd think by version 10 FF team would put these 2 functions into it by default. Anyway great addon please update for v10.

This review is for a previous version of the add-on (1.1).
