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:
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.
