I checked out Mozilla 0.9.8 for OS X last night—and was very pleased with how it looked much more like an OS X application than did previous releases. It doesn’t seem like so much of an oddball anymore.
However, on my machine there’s still something jerky and slow about the interface that’s just a bit too annoying to make it my main browser. I want to use it, but for now I’m still using IE, which feels smoother and faster. Nuts.
