The reason I'm posting here is because this problem only occurs with the Adwaita theme. It just began occuring today. I've even tried resetting Firefox, but it didn't fix anything.
Here is what it looks like:

This is a comparison between the Adwaita theme (left) and the Ambiance theme (right).
Adwaita looks Windows XP-ish, for some odd reason.
Is it possible to make Firefox on Mac look like on this screenshot (taken from official Firefox site)? Couldn't find this theme on the website. Is it some kind of platform-specific theme? I am running Firefox 27.0.1 and OSX 10.9.2
p.s. I know question is a bit stupid, but really could not find any tracks of that theme on addons portal
