Rated 4 out of 5 stars

I installed this 2 minutes ago on Firefox 3.0, Windows XP.

I just installed this because I am a long-time user of Alexa sidebar.

Quite buggy, as I can already tell you two!:
- Can not resize (wider) the sidebar on the left!
- The Sidebar (View / Sidebar) has no name! The name is BLANK, I mean EMTPY!

Usability:
- Alexa results are less relevant, BUT THE Alexa SIDEBAR is much more CLEAR, please compare to that! R U serious, you type www address with LIGHT GREY FONT?!

This review is for a previous version of the add-on (1.0.3).
