Wow. That's going to take like... every single piece of my firefox UI except maybe the location bar, and either reset it to the current defaults I can't stand or simply drop it all on the floor. Given that it's looking like I may have to rewrite a good chunk of the UI in an extension to fix this, I'm wondering if I'll even be able to find the time to upgrade.
Mozilla has been making some horrific decisions lately, and it seems they are going to be yet another business set to learn the hard way that surprising and pissing off users that you depend on for survival is a BAD idea, when they can leave for your competitor at any time.
Just about the worst thing you can do when users don't like your Cool New Design is to say "you'll get over it" and repeat how the features they cared about were removed.
I don't have much opinion about Australis. I was referring to performance regression, addon/extension compatibility. Mozilla has a lot of work to put into after enabling it in the release; I believe it's 29?
