You can always* request a new archive of a website. If you log in (warning: it has to load google code at least when registering) you can also request a screenshot (which I don’t know how you find later on, but right after you get a link) and recursive archiving with a depth of 1.
Interactive elements remain interactive nowadays, but it has limitations.
In some cases archive.today is worth a try too. It has workarounds for e.g. facebook, or at least in the past it had a fake account to be able to save facebook content.
But this one loads whatever code from yandex, so if that’s problematic for you be sure to block it. uMatrix is best for that task, probably uBO can do it too, the Firefox version I mean.
These sites are basically my “remote browser”, and often it’ll be even useful for others that I requested an archive. Quite often I’m requesting the first one.
mostly, but you can’t if the site was very recently archived, like in 30 minutes. Then there are some sites that are blacklisted for some reason but not much.
