Needs a small touch up for FF3.6 Rated 5 out of 5 stars
Attention. This theme does not grey out the empty websearch box & address bar in FF 3.6. There was a change in the XUL for textboxes which now don't have the empty attribute anymore, but isempty instead. So instead of textbox[empty="true"], you need to use textbox[isempty="true"].
This needs to be changed in the global/textbox.css file in the theme directory (those "in the know" know where that is).
Personally I tweak the theme in its Windows flavor even more by changing the top main menu highlight to solid color as was common in FF2 when used with "Windows Classic style". Also for some reason the dropdown buttons near every dropdown text input are missing on Windows which I mega loathe and have to change back to normal in every update of this ratchet theme.
The textbox feature has been fixed for quite some time now, in case you/others were still wondering if the bug still existed.
