Firefox 3.0 Has Arrived. Download!
Firefox 3.0 web-browser has been released! The new browser has much slicker (imho) user-interface, feels faster/lighter and is just plain awesome!
For FireBug users (i.e. any web-developer and designer?) out there: you need to manually download a new major release version, 1.2.0b4. Automated update of 1.05 won't work.
Don't know about Windows machines, but on Macs you can rename the existing Firefox to Firefox2 under Applications, before installing Firefox3 and that way you can keep running both in parallel (though not at the same time). Once you upgrade the plug-ins, you can not use them in the Firefox 2, anymore and you will start getting warnings. It's still useful for testing rendering of websites and making sure your HTML/CSS works in Firefox 2, though.

alternate profiles?
Have you tried creating multiple firefox profiles -- one for v2 and one for v3? I'd read some reports that this helped run both when v3 was still in beta.
I haven't tried it yet -- I'm looking for a guinea pig to verify it first :-)
Too much work
Nah,
too much work. Just renaming firefox.app to firefox2.app gives you the rendering engine and you can use it for testing. Granted, plugins do not work but - not big enough problem to worry, imho.
Good thing about FFX - it's no IE - things usually do not break with an upgrade and most users upgrade very quickly. I think 90% of Firefox users will upgrade in a month period, the most. I assume that's a benefit of Firefox not being an "enterprise browser" and upgrade being done by users themselves. When it's not left to sysadmins with superiority complex, things usually move quickly :)
