I'm not waving it off.  It's something which Mozilla has fixed in
their nightly update process which is not addressed in Fedora updates
for Firefox.  Mozilla nightly pre-stages the update and then does the
update on startup.  When combined with persisting the application
state across restarts it makes the whole thing painless.  Otherwise,
yes, it can be problematic, as firefox does runtime dlopening and such
and can end up inconsistent if you swap out files out from under it.
