Please add a new function Rated 2 out of 5 stars

This extension is not very useful now. The one thing you should do ASAP is to add ability to navigate through Ctrl+Left/Ctrl+Right buttons.

This review is for a previous version of the add-on (1.2.3).

You right, this feature is now present on the addon (version 1.3+).
Sorry, the addon should be updated before but i was waiting (like all of us) the new version of Firefox (3.5).
