Hi Gal,

I don’t know there is a direct equivalent but there is [Set Viewport Size](https://marketsquare.github.io/robotframework-browser/Browser.html#Set%20Viewport%20Size) which will let you specify the window size. with that you should be able to achieve what you want.

Dave.

Hi, There is not a keyword but it is possible.  
Try:  
New Browser ${Your browser here} headless=false args=[“–start-maximized”]  
New Context viewport=${None}

You can also try this if you need to use a direct path and have any https errors:

New Browser execuatblePath=/path/to/browser.exe headless=false args=[“–start-maximized”]  
New Context ignoreHTTPSErrors=true viewport=${None}
