Question

linux

I need an OS on Linux, where there will be only a browser, so that there is 1 tab that I set, how to do this?

Answer 1

Set up automatic login and start the browser in kiosk mode. for example
firefox --kiosk https://ваш.сайт

Answer 2

Look for autostart of the browser in kiosk mode, this is exactly how chrome can do it, there is https://porteus-kiosk.org/ , which is purely for this, it seems to be imprisoned, but this can be done with any distro in theory.
