does it launch under 3 seconds?
It takes about 12 seconds to load on my netbook. Opera loads in 1. IE in 3. Safari in 8 and Chrome in 4.
Is this compatible with a lot of existing add-ons? If so, is it stable enough for day-to-day use, or is the beta tag warranted?

I hate the person who thought of this.
I couldn't tell you how many times I've gone to hit the stop button in Opera only to have it quit loading a few milliseconds before I actually click the button and end up reloading the damn page.
I really, hate the person who thought of it. I'm afraid to even use the stop button now.

Even more important is how long it takes to shut down. 20,40,60 or more seconds (sometimes never!)? To date Firefox clearly has some kind of significant memory management problem.
I love the add-ons etc, especially for performance analysis, but basic start up and shut down have been poor. Hope 4.0 is improved in this regard.
The only thing that I hope has been changed is the matter of closing the firefox.exe processafter the program has been closed for over 5 mins, When ever I close mine (V3.6.6) I always have to go into the process's menu to manually turn off that file, then once that's done I can restart FF - lets hope the crash handler works now too :)
I love using FF, hopefully in this version, they have got it right ;)
[UPDATE:] I have just installed it, first impressions: Get rid of the orange firefox button, or at least give me that option! Load time was 8 seconds ~ not too bad (2nd start was only 2 seconds! Cool, certainly a + point), but I shall have to play with it for a while to see what I think.
Get rid of the orange firefox button
I`ve just popped FF4 Beta 2 on one of my small laptops. I don`t see any orange button, layout looks pretty much the same as the current version. I can see changes to the add ons layout though.
