The 3.01 version exhibits the bug know as the 1px jog when attempting to center an image on a page. The result is the placing of a border on one side of an image, such as a banner, etc. This bug did not appear in version 3.0.

Unfortunately I cannot provide a screen shot as I had to uninstall 3.01 and reinstall the 2.0 version (is there not an option to install 3.0?).
I spent hours agonizing over this and nearly lost a client over it. A Google search gave me this:
http://support.mozilla.com/tiki-view_forum_thread.php?locale=de&forumId=1&comments_parentId=109927
So, I knew it wasn't just me! Sound like a rounding error when attempting to resolve something less than a pixel - when using the "margin: 0 auto;" to center-align an image in a page. This behavior was not present in 3.0.
Sorry I can;t offer more evidence than this but it should be very easy to reproduce for someone with 3.01 installed:

This shows the website in question with Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1a1pre) Gecko/2008071903 Minefield/3.1a1pre on Vista.
Layout guys, is this an actual bug? Or just unintended effect?

Well, since it's Firefox it must be an "unintended effect"; it would only be a bug if is was IE? :-O
No, I mean an unintentional result of changing the way layout happens internally; that is, it might not actually be a bug, but correct as per the spec. Firefox 3 changed the way internal layout was computed, partly to support full-page zoom; presumably IE7 had to do something similar.

lol :-) Either way, it now involves the hack of adding 1px to the body tag. Hacks are unacceptable since they cause sites to break at a later stage. You make a very interesting point though regarding the zoom. IE7 works just fine; IE8 is not ready for prime time yet and I also had to uninstall it.
Hopefully, his can be fixed. I was very impressed with Firefox 3 and noticed the speed increase straight away :-)
