I would like to have Windows open a file in Firefox with a custom build command. I have a separate Firefox profile with development extensions I’d like to use for it. This works:

"cmd":"C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe","$file"]

But it only uses the previously used profile. I’d like to specify the profile, but this doesn’t work:

"cmd":"C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe -P \"Development\" -no-remote","$file"]

How am I supposed to define the startup options, -P “Development” -no-remote ?
