I want to set a shortcut to open firefox to my outlook web access, and treat it like an application, not a firefox window. I'd like it to not have tabs, and ideally not the url bar, or anything but the outlook window. Is there a way to do this, and still use firefox normally when I call 'firefox' from the command line. I'm thinking of something like: 'firefox --single-app https://mail.theserver.com' or 'firefox -P outlook' Ideally, it would work if it was the first firefox instance or if firefox was already open. I would know if it wasn't already open, so odd behavior for calling it twice is fine by me. I'm basically trying to replicate the functionality of the surf browser, but with firefox being the actual browser, with all it's features.
