How can I open multiple "non-merged" firefox windows? With IE, I would use the "-nomerge" option. Is there something similar for Firefox?

I use a website in my daily work activities that I need to have multiple sessions of the website open at any given time. Natively, I cannot have multiple sessions open in a single browser (separated tabs or separate windows) without one session taking over the other. Internet Explorer has a command line option (-nomerge) that will allow me to accomplish what I need. The target line of the IE shortcut properties would look like this: "C:\Program Files\Internet Explorer\iexplore.exe" -nomerge

Is there a similar solution for Firefox?

I am running Windows 7, IE11 and Firefox 26

Thank you in advance, Robert
