Is there any difference between "firefox -p -no-remote" and "firefox --ProfileManager"?

When switching to another profile, I always use "firefox -p -no-remote" command in terminal in ubuntu 14.04 LTS. Then I read a MDN article named "Multiple Firefox profiles"(https://developer.mozilla.org/en-US/docs/Mozilla/Multiple_Firefox_Profiles) and here it instructs to open profile manager with "firefox --ProfileManager" command.

Now my question is, are both commands have different accessible priority in Profile Manager?

Chosen solution

The -no-remote switch with the -P for Profilemanager switch is so you can start a second instance of Firefox. You cannot start another instance of Firefox with same Profile or just by starting Firefox with Profilemanager.

The last Release you could start a second instance with just Profilemanager was Firefox 1.0 (1.0.8) and earlier Releases. The -no-remote switch has been in use since Firefox 2.0 Release.

The -P and -ProfileManager do same thing in starting a first instance of Firefox with the ProfileManager.

Note that you may not be able to pass links (i.e. double-click a link in a File Manager or email program) to a Firefox instance that is opened with the -no-remote command line switch because this switch hides this Firefox instance.
