> I wish Firefox Nightly automatically did the new-profile thing like Firefox Dev Edition/Chrome Canary does, though. Not being able to run them side-by-side out of the box is quite annoying. I don't know about Nightly or the most recent release, but the following has always worked to open the profile manager and setup a new profile: firefox.exe -p If you want to run two instances of Firefox side-by-side, start the first instance and then use the following command (again, untested on the latest releases and on Nightly): firefox.exe -p -no-remote

Please use --new-instance instead of --no-remote.

  Not quite sure about this advice. MDN documentation on the command-line options[0] currently references a WONTFIX'ed bug[1] - that option does not work on Windows systems. Unlike --no-remote which works consistently across platforms.

      Actually friday20 might be right on this one. The remote code is very different across platforms. The way it works on non-Windows/non-Mac is very different, and it's possible that --new-instance doesn't work as expected there. On Linux/BSD/etc (everything that uses X11), --new-instance should be prefered.

  Thanks, but why?
