[Bug 1226952] Re: Option -ProfileManager does not work without (bogus) -u

[Chris Coulson]

This isn't really a bug (or certainly not something we're going to
change in Ubuntu). Firefox is single instance, so when you try to run
new Firefox instance when there is one already running, the entire
command line is delegated to the already open instance.

If you want to use "-Profilemanager" when you already have Firefox open,
then you need to also use "-no-remote" to ensure that a new Firefox
instance is opened (which is documented). We even state this in the
manpage that we add to Firefox.

"-u" is not documented because it's an internal implementation detail.
It "works" in your case because you are using it incorrectly which
results in the remoting of the command line failing.
