This is a build of Firefox on the reflow branch, a development branch on which I'm making major changes to the way Gecko does intrinsic width computation and incremental layout, showing the Acid2 test being passed.
If you're curious about the reflow branch: it's still not ready for testing, although hopefully it will be in a few weeks (once form controls can be turned on again and the table code gets a bit more work).
Update: These changes landed on the trunk on December 7, 2006, so the latest trunk builds now pass the Acid2 test.

@mu22le: That is Metacity, Gnome's window manager, using some incarnation of the clearlooks theme. Probably on Linux (or *BSD. Or Solaris).

This is not a fake. Nor is it the normal 3.0 alpha build (the 3.0a1 build still does not pass Acid2).
You can see for yourself by downloading the installer from Mozilla:
ftp.mozilla.org/pub/mozilla.org/firefox/nightly/experimen...
Open this folder, locate the latest build, and install. I'm typing this message in the 10/22 reflow nightly build right now. And Yes, it does pass the Acid2 test.
I can't wait till FireFox 3 is released!

Yes, it IS real! :)
Get FIREFOX 3.0 ALPHA (this is direct link to installer), and see this yourself!
