I was resizing firefox to fit a blank area of my screen using Metacity's shift-resize snapping resize feature. While doing this firefox crashed. I tried again, and it seems as if firefox will crash any time it is resized to a 0 width.
We just updated the Firefox version in Fedora/development from 2.0 to a 3.0 pre-release version, which improves performance, memory usage, and fixes many bugs and crashes. Closing as CANTFIX since we aren't fixing bugs filed against 2.0 now that 3.0 is in. If this bug is still present in rawhide using a Firefox 3.0 version, please re-open this bug. Thanks and Happy Holidays
