Firefox is my main browser and I love it, but I totally see what you mean. Chrome looks just right out of the box, but even a small line in Firefox UI makes it irritating. I have several userChrome CSS changes to make it look exactly as I want. All these taming took me some time, but it's totally worth it because this is a software you spend a few hours every day on.
