Well Firefox 4 Beta is here and it looks pretty nifty. I downloaded it and have been playing around a bit on it this morning, seems to be lots of cool new add-ons and features. There is also a feedback button in the top right where you can let them know what you think about it.
Check it out now here

I'm curious if they fixed the memory leak that drives me nuts with Firefox, some how I don't think so.

Ditto. I'm gonna grab it and try it out though. I feel it's my 'duty' running a site like GD. 
As long as it'll let me run it concurrently and not screw up my FF3 install.
Well, I'm on it right now .. first impression, it seems pretty fast, but that might be (probably) because 98% of my addons are disabled (not supported yet as expected).

Yeah that was the reason I didn't upgrade. Are you going to let it run for some time and see what the memory hog is really up to?

Yep, I have to take off in a bit so I can just leave it running. Not sure if it'll happen though since it may be related to having the addons enabled, but we'll see. I've also noticed I think they may have copied Chrome a bit with the way they handle new tabs now.
That didn't take long. I loaded up ONE Youtube video (The Beatles: Do You Wanna Know A Secret) and ... locked up tighter'n a ... uhhh ... I only know dirty metaphors for that one ....
So I had no choice but to Ctrl+Alt+Del. Whelp! *wipes hands* That's it for me! I'll wait until it's more stable.
"This second beta doesn't offer any drastic changes in design or functionality from what my hands on with Firefox 4 Beta 1 revealed, but the Mac version now gets tabs on top the way the Windows version did in beta 1, with Linux
to follow at an unspecified date. The new version also lets you turn a tab into an "App Tab" from a right-click context menu when your mouse cursor is over that tab."

Cool thanks for the heads up. I think I might wait for them to work out any bugs before I upgrade and to make sure the add-ons that I have upgrade with it. I'm curious if they fixed the memory leak that drives me nuts with Firefox, some how I don't think so.
