You need to install the codecs, there’s a way to do it on ubuntu, just google search it (and there’s an option during installation to do it too). The N150 cpu and its integrated gpu is not a problem for your codec problem, it’s a matter of installing the right software.
Yeah, snaps won’t be able to access the “external” codecs (outside their jail). So either install the official firefox package from the firefox site, or chrome.
