I don't see any cool alpha blending effects in that screen shot. Am I missing something or are they not there?

No alpha-blending yet, just GIF transparency.

I want a binary of this beast! Any idea where I could find this?

Are all of the linux screenshots using GTK? Or are they still using Motif?

Two questions: First I thought that Mozilla wasn't meant to have the Netscape 'N' logo on it as it is reserved for officially branded Netscape Communicator/Navigator products and Mozilla has it's own throbber.

Second I thought Mozilla was getting rid of its toolbar full of buttons for a more simpler approach. In other words a default of only back forward reload and stop. With the option to customise it to the preferences.

My currently compiled version of Mozilla (lesstif + old layout engine) has both the Mozilla throbber and the customisable toolbars. But I am excited in the progress GTK is making and I personally think the move to a free toolkit was a good thing. It's good to see we're catching up with the Windows version.

These screenshots are of the GTK+ version of the XPFE. Currently, the XPFE doesn't support the 'Customisable Chrome' that Mozilla did, but that is being worked on (in a different manner: DOM rather than RDF). In any case, if you're a coder, help out; if you're a user, test and submit bug reports.

a complete rewrite of the config chrome? I guess I'll have to put my Mozilla skins page in the locker until I get more info on the new setup

I was going to start distributing newlayout+gtk binaries, but the functionality isn't really there yet. The url location bar is not hooked up yet, and clicking on most links does not work. But the progress in the last few days was so much, that these issues'll be fixed soon, I imagine.
