Load specific profile from command line

more options

I have two profiles. A and B. B has been set as default using ProfileManager. I have made shortcuts to start each profile as follows:

"C:\Program Files\Mozilla Firefox\firefox.exe" -p A -no-remote

and the other one as:

"C:\Program Files\Mozilla Firefox\firefox.exe" -p B

What I want to do is start another but the default profile, when I open a specific filetype (windows 7).

The current association for the .html file is:

C:\Program Files\Mozilla Firefox\firefox.exe

with command line arguments as follows:

-requestPending -osint -url "%1"

This opens the specified url as the default firefox profile (B in my case). I want to open each .html extension using the A profile, and any other extension that loads firefox as the B profile.

Mozilla, states that -p and -requestPending -osint cannot be used at the same time.

How do I open another profile for a specific filetype?

You want to open a 2nd Profile while the first Profile is already running?

Not exactly. I've managed to do this using the: -no-remote to the second profile, that is not the default. The problem is that I cannot create a command line that Windows will use to open a specific filetype using a profile other than the default.

Sorry, I'm not sure how that would be done, or if it is even possible.
