If you are referring to the background, indeed the colors change on purpose. It would be cool if that wasn't on purpose. As for browsing issues in Firefox, could you clarify the issue? If it's around using the Browser app, it is just an iframe so many sites will not load in it.
yeah i'm in the process of. why? are you interested to try? if you are send me a hello to cris@dosyago.com and I can send you a link when up and get your feedback if you're free :)
Technically you could fake it with an iframe if puter is served with the correct frame-src CSP rules. But for a full browser experience you’d need a backend and a remote browser.
