[I saw some of the other suggestions but I got confused about which was the
original problem so I am responding to the original question so I can more
easily bottom post my reply.]

I see this happen on my (Android) phone all the time, so I have my
preferred browser (Dolphin) set to clear the cache every time I exit it,
which usually helps. I have presumed it is a memory issue or something like
that, but it seems to especially affect sites like FaceBook that load LOTS
of ECMAscript/JavaScript.

I assume you have cleared the cache in Firefox and Chrome, but if you
haven't, try at least clearing the caches. You might also clear your
browser cookies. In Chrome/Chromium you have to display "Advanced Settings"
and click the "Clear Browsing Data..." button. I would start by choosing
just the cache files. In Firefox, in recent versions it's under Preferences
--> Advanced --> Network and click the "Clear Now" button next to Cached
Web Content.

If that doesn't help, another thing you can do is to create a new user
account and try the sites in the new account. If the sites work correctly
in a brand new user account, then there's something in your existing user
account that's fouling up the loading of the sites, such as a corrupt
extension.

If the new user account helps and you want to quickly replicate that "fresh
and new" experience in your regular account, log back into your account,
make sure the browsers are closed (being aware that Chrome has a setting
that lets it run in the background so you may have to kill it or turn off
that feature in Advanced Settings.) Once you are sure your browsers are
closed, open a file manager (or a terminal) and move the hidden files with
your settings in them. (I say move them rather than delete them right away
in case you decide you need something in them. Moving them either to the
Desktop or the Trash is OK, and you can move them back if you need to.)

For Firefox, move ~/.mozilla/firefox/
For Chrome, move ~/.cache/google-chrome/
For Chromium, move ~/.cache/chromium/

Launch your browser, navigate to the sites, and everything should be OK.

Let us know if that helps!
