Firefox launch in full screen

more options

How can I launch Firefox in full screen mode? I created an executable file for simultaneously launching two browser tabs at once. He works. But I need the browser itself to open in full screen mode. In this form, as if the "deploy" button was pressed. Please tell me what you need to add to the lines of the executable file. Or maybe there is another way. Here is the data of the executable file: start "" "D: \\ Browser \ firefox.exe" https://www.google.com/ https://yandex.by/

There is a command-line switch called -kiosk that should in theory open a URL "full screen without user interface." I don't know whether that would be helpful; I've never tried it myself.

I know how to use the context menu, and also know how to use the hot keys. Also using the "-kiosk" switch --- I know that. But when you start using "-kiosk" nothing comes out. I think because the version is portable (this key works on the installation version) and in addition one of the tabs stops opening. In addition, starting with this key fully expands the window on the display hiding the panels and making it difficult to use the browser’s functionality. The task is this: so that the launch of the executable file would produce an effect like clicking on this element:

Hi la.zvezdopad.la, PortableApps has a support forum for its build of Firefox:

The term for the window state you want is "maximized." Firefox may or may not remember the last state of a window ("maximized" versus "restored"/"resizable"), and may or may not apply that to restored windows, external links, or at startup. I don't keep careful track of when it remembers and when it doesn't. Maybe you've figured out the pattern.

Users have reported that enabling privacy.resistFingerprinting definitely prevents windows from being maximized on startup.
