Today, mysteriously, firefox is working again. I have not rebooted the system, logged out, made any system changes, changed any firefox config parameters, or installed or removed any software since my previous posting. Nevertheless, today I can start it up, open multiple tabs and windows, and all the usual stuff.

More data. The regular Firefox install is working. The previous Nightly version continued to fail. Just now I installed the current Nightly version. It also fails to start, with the same symptoms as before.
