Question about Starting Firefox on Windows 10

more options

Hello, I have firefox version 92.0.1

I am starting it from the command line cmd.exe

I would like to set the window size and window position on the command line before it launches.

What are the parameters to set the position, height and width ?

Thanks Coby

Hi Coby, I don't know whether you can set those parameters on the command line. Firefox generally reads information from the xulstore.json file in the relevant profile folder.
