I can find no recent documentation on command line options for the Firefox Browser. All of the information on this appears to be out of date or just does not work any more (in the latest version June 2021). Is there any documentation on this anywhere that is correct for the current version of the browser? I am specifically trying to run firefox with command line options on Windows 10 but I do not see that that should make any difference. The only option I can get to work is starting firefox with a specific URL; even then I have to change the browser settings to get that to open a new window; because the browser settings override the command line option -new-window

I too need a CMD / CLI to set firefox offline and set it online - not just necessarily starting a new instance offline

   I use CMD to switch using different NIC's for work and personal browsing.
   netsh does this brilliantly - and script-able with an icon for double click; perfect solution.
   Now the issue is, when i make office NIC offline, and iPhone NIC online and for a few minutes i need to switch (offline iPhone and online NIC); i have to remember to make firefox offline.
       If i don't, and firefox is in online mode, it will then communicate with work NIC, and the proxy server at work will be hit with blocked sites.
   If there is CMD equivalent, i can add to my script, so that when i execute the work NIC online function, one line will set the firefox browser offline as well. All this assuming only 1 instance of firefox is running ;)
