Rated 1 out of 5 stars

Did not work with new firefox. Icon doesn't do anything. No way to troubleshoot.

This review is for a previous version of the add-on (3.0.2). 

3.0.3

Could you please try version 3.0.3, located here...http://code.google.com/p/uctb/downloads/list
or you could wait until it is approved for AMO.
