How to open Browser with 2 default Websites and define Whitelist?

[blueicehaller]

Hi,
on an Raspberry Pi 4 I connected the following Display with Touchscreen:
Iiyama ProLite T2735MSC

Previously I used Porteus Kiosk on x86 which is using Mozilla Firefox and is able to

1. open minimal Browser in F11 Fullscreen and show 2 Tabs (default Webites) on startup
2. Maintain a Website whitelist
3. Hide address field

Is it possible to do the same with Chromium or Mozilla Firefox on Chilipie?

I already defined 2 default Websites.

Thank you in advance.

Update 24.08.2020
Here is my current situation:

1. In Chrome settings I defined the default Website to show on startup
2. I do this in the Router settings (AVM FRITZ!Box, Parental controls / Kindersicherung) where I can maintain a global whitelist and assign this additionally created profile devices based on the MAC-Address
3. chilipie-kiosk with Chromium starts in Fullscreen without address field

Further I'm using the Chromium Extension Url Slideshow on the seconds Raspberry Pi connected to an TV w/o Input device (Keyboard/Mouse/Touchscreen) to display the Website (115 seconds) and Logo of the Organization (5 seconds).

Sorry for taking a long time to get back to this.

There's no built-in support for showing 2 sites at the same time, unfortunately.

As to white-listing, you can definitely do something on the system level (or maybe using some Chrome extension?). That said, the kiosk isn't really hardened for adversarial users - if someone has physical access, they can probably break out of the browser.

That's OK. I updated my requirements with my current situation.
