Rated 5 out of 5 stars

Great enhancement and fine customizable. Only problems I found on some Java based sites, where glass effect makes crappy readability on them (An example here: http://ibmtvdemo.edgesuite.net/servers/power/demos/power_730/index.html), and I did not find the way how to customize it for eliminating that effect... -|-
Modified: Yes, it is happen when "Remove white color gradient from window" setting is on. However when I disable that option, it makes a sharp glass transition on Vertical toolbar add-on :-) But it is only cosmetic problem and I know there are certain system limitations... Anyway, excellent job and deserved 5 stars.

This review is for a previous version of the add-on (1.1.1). 


Is it possible that you have enabled the "expert setting" to remove the window gradient (the very last one at the bottom)? That setting breaks application plugins like Adobes PDF Plugin too. Besides that setting no other setting breaks the site your posted a link to for me.
