Breeze style tabs for Firefox

Recently I was struggling to make tab close icons look closer to Breeze theme. Now I managed to make tabs look Breeze-ish too! The icon rules are also better now, opacity works without superposition problems:

Firefox tabs a-la Breeze

Firefox tabs a-la Breeze - circular icon

The userChrome.css is very messy and probably redundant, but hey, it works:

Just make sure you disable any other tab modification add-ons and userChrome.css rules.

PS: I also included slightly more appropriate icon for Xclear add-on.
