So, it just came out, either today or yesterday depending on where you live. I have to say, I'm not terribly impressed. They've made it feel and look more like Opera, which is a good thing if you're an Opera fan, but if you like the way Firefox has been doing things in the past, it could be a bit of a disappointment. Everything seems to feel clunkier. And there's a certain lack of feedback in the interface that I feel missing. I get that same kind of feeling from Opera, and I can't quite put my finger on why. In some ways, it is snappier, and in some ways it isn't and actually feels like a step back. Some of the things like the Add-on manager for instance, which uses an entirely different interface than before are actually kind of sluggish. And the statusbar seems to have been borrowed from Opera as it behaves exactly the same way. Again, fine if you like it that way, but I see no way of changing it and it actually makes me feel a little uneasy, which is related to the lack of interface feedback. Anyone else have any other thoughts to share?
