get external program to launch Firefox with correct profile

more options

I launch Firefox with -p switch and profile name. How do I get Firefox to choose that profile as default without using that switch? - needed so that when my mail program launches a browser (as specified in Windows), it launches Firefox with correct profile. At present it uses correct version of Firefox (I also have a Minefield beta installed) but wrong profile.

1) External programs are going to launch the Profile that is showing as the Default=1 Profile in the profiles.ini file. If that particular Profile isn't even listed in profiles.ini, that's your problem.

2) If that Profile is already running using the -no-remote switch to launch it, it won't be seen. That switch basically tells Windows to ignore that process.

Are you also using the -no-remote switch?

Is that Profile not listed in the profiles.ini file?

Thanks, the_edmeister. To answer your questions, No, I never use the -no-remote switch. My QuickLaunch shortcut specified both the version of Firefox (by calling it with full path) and the profile (by using the -p switch).

My profiles.ini starts with the entry StartWithLastProfile=1 It listed three profiles, including the desired one, but it did indeed have Default=1 against a different profile. I moved this line to the end of my desired profile - why didn't I do that earlier? - and lo, the external mailer now launches Fx with the right profile, and the shortcut works even without using the -p switch to specify the profile. Problem solved. Thank you.
