slow startup is because Firefox looks at all installed extensions to
determine whether an update is available and then Firefox looks to see
if a newer version of Firefox is available. The more extensions, the
longer the startup delay. You can configure this...

Firefox => Edit (menu) => Preferences => Advanced (tab) => Update (tab)

Firefox creates a 'lock' file -
in .mozilla/firefox/$YOUR_SALTED_PROFILE/.parentlock which is intended
to prevent multiple launches.

Multiple launches often occur when double clicking to start from a
launcher rather than a single click or 4 clicks when a double click is
sufficient.

I run into this far too often because I sysadmin a network with a lot of
less skilled computer users. This should probably be improved because
the cure seems to be as bad as the problem.

pardon my ignorance, what is FEBE ?

I find all of the language extensions to be pointless for my usage but I
can't tell if it's because my system/profile has existed for quite some
time and has been upgraded from like FC-4, FC-5, etc.
