 > After reverting back to default extensions (HTTPS Everywhere, NoScript,
 Torbutton, TorLauncher), loading http://www.nationalgeographic.com/ and
 allowing all JavaScript there, I still get just a blank page.

 > The security level is set to "High". Setting it to "Medium" works around
 the issue. This is strange, since according to the security slider window
 the only changes applied are that SVG images are disabled and website-
 provided fonts are blocked. Neither of these should be necessary to render
 the page in its entirety. For example, the banner image is not at any
 level inside an SVG element.

 Okay, the HTTPS Everywhere related error was due to a slightly outdated
 extension version (I did not update it after extracting a clean 7.0.4).
 And, yes, allowing SVG content allows the page to render properly. I guess
 what is happening is that the site is trying to load some SVG stuff very
 early and stops then not rendering other elements that are not SVG
 dependent. Anyway, nothing we can do about it.
