Firefox has looked awful on Linux for a long time. I'm excited to see a consistent design on every OS, and I've been primarily using the UX build for months. A lot of people say this looks a lot like Chromium, but I don't find that to be the case at all. The background tabs aren't rounded at all, while tabs are shown to be rounded on mouse-over. It's a significant improvement over Chromium's approach. I'm not a tremendous fan of the rounded design, but it's certainly an improvement over the previous design.
