Brave setup as kiosk or Full screen. Opening a new page using js window.open no Full size

Browser Support Desktop Support

Brave is started in full screen (or as kiosk). All works correct. When a new window is request using Javascript window.open, popup-mode, the new page has not the status as full screen.

How reproduce ?
Open Brave
load url (for me it is a local app in php, html, mysql on xampp) showing pictures
To get full size image, hit a thumb. A js is launched containing the command window.open with spec to act as popup
The retained image is full-sized, but not fullscreen. The new window, page does not herrit the settings of the parent browser.
ex. https://www.fotospotter.be/insect.html

Is there a setup so child-pages herrit properties of the parent ?

In Edge, this works:
setup: make a shortcut to edge on the desktop, and open properties add to target:

–kiosk --edge-kiosk-type=fullscreen -no-first-run https://www.fotospotter.be/album.html
Save and run this shortcut
The js-script using window.open is fully functional concering browser-kiosk-setup when fullsized image is requested.

Create shortcut to brave and add to target-propertie: --kiosk
Save and run this shortcut
The js-script using window.open is NOT fully functional concering browser-kiosk-setup when fullsized-image is requested.

Thanks

Thanks for this exhaustive list. I already tried some of them, but still when using javascript window.open to create a new page, fullscreen is not used, set (manually you can the hit F11 to obtain fullscreen but this is as I said, manually).
It looks if the new created webpage does not herrit the paraeters entered at the command line to open the first webpage. Or, is there somewhere a key which must be activated so, new incognito pages herrit these commandline parameters ?

I now use:
-kiosk --start-fullscreen --start-maximized

Look over:

See what results, by starting BB from the command line.

Problem remains. I looked to Javascript window.open info. For as far I understand, that function opens a new webpage as a tab or a popup, but they mention that not all stuff that initializes the browser is used. So, I assume that the kiosk-switch or fullscreen-switch isn’t ported for the chromium-engine? In Edge, it does.

In a Brave Browser New Window, go to:

brave://prefs-internals

Do not edit that data, but search for:

  • fullscreen
  • kiosk
  • maximized

If, somehow, Brave Browser still includes the function, you might find an indication.

Also, you might find info at:

I compared that info from Edge with chrome, brave. All seems equal, execpt that in edge there is a switch added in a group:

I think that the parameter ‘app.window.fullscreen’ is an indication to permit a fullscreen herritance in js.
But, I have not enough knowledge about this all.
This term we can not find it in chrome, brave, firefox, …
