Can you try starting with `firefox-esr -safe-mode`?
That works.
If that works, can
you then go to about:config and switch javascript.options.ion to false,
then restart without -safe-mode?
That crashes.
If that works, stop there. If it
doesn't work, can you try -safe-mode again, and switch
javascript.options.baselinejit to false?
And now it works in non-safe-mode!
Incidentally, since you're talking about Javascript, I thought it might
be relevant that I'm using the NoScript add-on, so I thought I'd try
disabling that (which worked), and setting
javascript.options.baselinejit and javascript.options.ion back to true.
When I switched javascript.options.baselinejit back to true, Firefox
instantly crashed. (But, of course, it's recoverable again via -safe-mode.)
Setting only javascript.options.ion back to true *doesn't* crash
Firefox, or prevent it from starting.
