As far as I could determine, there is no native way to open a page in a Firefox multiple profiles environment when the profile is already open. On the Linux shell I am trying something like:
firefox -browser -new-window -P "development" http://google.com
No matter which arguments I add, I don't get around the message:
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
It would be nice, if I could open a new window or even reuse a named one in a specified profile from an IDE, namely Netbeans 8.1, to debug some code.
Is there some tool, e.g. an addon, allowing me to do so?
