Doesn't work for me Rated 1 out of 5 stars
I have installed it with tb 3.0.1 in the most recent version (1.6.1):
When opening a bugmail generated by our corporate bugzilla (Version 3.0.3) i see this additional frame on top of the bugmail but i don't get any status information.
Maybe it's because you have to be logged in to view a bug in our BZ installation.
I'm pretty sure that this extension is very useful and I'd like to have this describes feature available in my TB but as I have it now it's as useful as a dead brick in the basement.
