Why has Firefox been so slow to slim down its UI? The back button is still way too big and the button colors not subtle enough. A browser should disappear into the background to some extent. It's just a window into the interwebs after all.
The back button is intentionally bigger as it is one of the most used buttons in a browser. In accordance with Fitt's law, the size allows a user to get to it quicker than a smaller button.
I understand the logic of the bigger back button, but I think it is a poor choice. It's rather awkward-looking, but more importantly it causes the entire toolbar to be several pixels taller. It's an amazing waste of space.
Thanks. I don't use Firefox much anymore (I keep it setup to use the corporate proxy for the few things that need that), so I'd forgotten about that option.
Sure, but many like the current default -- on a netbook, I used small icons, but everywhere else I willingly sacrifice a couple of pixels for an easier target.
