Rated 3 out of 5 stars

It does what it says on the box. It's nice that you can actually do more things with a click.
However, I noticed that, after disabling the add-on, the button doesn't come back to his original flashy orange color but stays rather dull =( =)

This review is for a previous version of the add-on (0.8.1-signed.1-signed).

Does the change in colour persist for you after restarting Firefox?
This is not a restart-less add-on.
