I use Firefox as a secondary browser on my Macs and primary browser on Windows and Linux, but I agree. It lacks polish, and its UI feels “off” in ways that are difficult to articulate. It’s probably fixable, though. One of these days when I have some surplus time I’d like to grab a copy of the Firefox source, see how practical changing its UI is, and figure out if the root cause of lack of polish is technical or organizational. If it’s the latter a fork may be in order.
