Firefox 54: Can't launch profile manager if firefox still running
I want to launch 2 instances of firefox :
- one with profile A - one with profile B
I works if i specify the profile with -P.
It does not work anymore if it launch the second instance with --ProfileManager to choose the profile: it will launch a standard firefox instead.
Regards.

You need to open the second Firefox program as a 'new instance.'
C:\PROGRA~2\MOZILL~4\firefox.exe -no-remote -new-instance -new-window http://comicskingdom.com/conceptis-kakuro/today
Usage: C:\PROGRA~1\MOZILL~1\firefox.exe [ options ... ] [URL]
where options include:
-h or -help Print this message. -v or -version Print Firefox version. -P <profile> Start with <profile>. -migration Start with migration wizard. -ProfileManager Start with ProfileManager. -no-remote Do not accept or send remote commands; implies -new-instance. -new-instance Open new instance, not a new window in running instance. -UILocale <locale> Start with <locale> resources as UI Locale. -safe-mode Disables extensions and themes for this session. -console Start Firefox with a debugging console. -jsconsole Open the Error console. -browser Open a browser window. -new-window <url> Open <url> in a new window. -new-tab <url> Open <url> in a new tab. -preferences Open Options dialog. -search <term> Search <term> with your default search engine. -setDefaultBrowser Set this app as the default browser.

Using the -no-remote in the command line to open another Firefox instance should be sufficient to get the Profile Manager. Otherwise the Firefox startup code will find an already running Firefox instance and (re)use it.
