A Very Good Awesome Bar Helper Rated 5 out of 5 stars

Adds a very useful function to the less then awesome Awesome Bar.
As for Honkerq's comment about it not working with Fission well it is working for me on two different machines both running Fx v3 on one and the trunk on another along with "Fission" and "Enter Selects" is working fine.

This review is for a previous version of the add-on (4).
