Please note the creation of Bug #427024, using a very recent release of Firefox 3.0pre. That bug provides both a sessionstore.js file and firefox log files for a reproducible (at least within an existing firefox session) for the "window unexpectedly destroyed" and the "untitled window" problems using Gmail, which means the problem is being generated using Javascript -- this is slightly different from many of the problems reported under this bug which are typically generated by window redraw commands from HTTP timeouts (sometimes used by news providers, advertisers, etc.).
