No doubt this is a high class theme.

You have been VERY thoughtful for a lot of the details, example from the context menu: http://i279.photobucket.com/albums/kk133/arimfe/reincontext.png
It looks good when the icons have their separate space, I like that detail a lot. Things like this makes it a top tier theme.

So far I have only noticed 1 bug in tabbrowser.css
The line says:
.tabbrowser-tab[busy] > .tab-image-middle > .tab-icon > .tab-icon-image {
But if you change it into:
.tabbrowser-tab[busy] > .tab-icon-image {
It will work like you intended.

I have modified a userstyle here: http://pastebin.com/f3377b09f
In case some people want a temporary fix, the code can be used with the Stylish extension.

On another note, I really like all your icons too, you have done a good job with them and they fit well with each other. All the icons I have from other extensions doesn't fit in, so I used this extension to hide them: https://addons.mozilla.org/en-US/firefox/addon/6690
And that extension had an ugly icon too, so I did this: http://i279.photobucket.com/albums/kk133/arimfe/QuickToolbarsicon.png
Your icon looks much better ;)
