Review of A Blue Fox Theme 3.5.2.08.11.09:
Now this is more like it! Now get yourself some custom Blue Fox icons for Places, Add-ons, and Options.

A minor nitpick (may carry over to your other "A ___ Fox theme" themes): Active and inactive tabs have poor contrast.

This review is for a previous version of the add-on (3.5.2.08.11.09).
