That appears to be the end for Mozilla as a web browser.
I was never a fan of large applications like Netscape and Mozilla in the first place. Having too many functions and features all bundled into one app was meaningless to me since I was using smaller and better stand alone software to do the same jobs already.
The up side is that Firefox and Thunderbird (and hopefully Camino) now have the full attention of all of Mozilla's developers.
