Hi, I need Firefox to open a window using a particular profile due having multiple logins to the the same website. However, I'm running into a Catch-22. I need it to also have the same behavior as if I use the "default profile" where it just opens a new tab if I try to open a second link. BUT, it needs to be with the appropriate profile. I've tried two different command line arguments and fail both ways: [FF path] -no-remote -P [prof1] This does what I want as long as I only open one link and then immediately close the window, but if I open another link before closing the window, it gives me the "Firefox is already running" error [FF path] -P [prof1] As you probably already know if you're savvy enough to help me with this problem, this ignores the profile and uses the default profile So my question really is this: If I have multiple instances of FF open using different profiles and need to open another link from the command line in a new tab in a specific one of those instances/profiles, is there a way to do that? Thanks! == This happened == Every time Firefox opened == always
