at last Rated 4 out of 5 stars

1. at last firefox has such addon
2. pls simplify the UI, only one arrow is enough. (no need the close/go down button)
3. and pls make the button background more simple, no shads/transform... etc
4. no other addons install(x-note?).
many many thanks!

This review is for a previous version of the add-on (2.1.1-signed). 

Hi Ken,
I'm currently working on a kind of UI that you suggested.
But it will have more features along with what you suggests.

And It definitely doesn't installs any other add-on. I don't know why the other guy wrote that.. :)
