I tried a Edgy Live instal tonight and it started properly (I didn't complete the installation since I didn't want to reinstall my OS tonight). So going from 256mb to 768mb of ram on this laptop solved the problem in Edgy that I had with both the Live Installer and Firefox.
So in my case all signs seem to point toward the fact that 256mb of ram is not enough to have a LiveCD session that works correctly and let you install from it. -- [Edgy] Desktop CD stalls/hangs when "Install to Disk" is double-clicked https://launchpad.net/bugs/60897 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
