I recently spent a bit of time at work seeing how well @webrecorder@digipres.club 's (excellent) Browsertrix and ArchiveWebPage work at archiving Facebook posts:

It looks like the automated behavior for scrolling and interacting with the page may need adjusting. But more worrisome is that even when content has been archived, and successfully returned to the browser during replay there is some FB JavaScript that is preventing the archived content from being added to the page?
