Is it truly faster? I don't know. I do know it feels faster and in this context feelings trump facts when it comes to most users. I'd also add that a developer edition sounds good but I'm not sure if actually is a good idea. While its true the addons are what bogs down speed, having separate editions makes Mozilla's job harder and it will make the temptation to continually add new developer pet features greater which can only hurt in the long run. A better option might be to simply have one, stripped down edition with optional extensions just like how things pretty much are.
