Videos & galleries on guardian.co.uk don't load it seems

I'm using FF Nightly 22.0a1 (2013-02-24) with NS 2.6.5.8 rc3. I've just noticed that, on the guardian.co.uk site, image galleries (think they're hosted by twitter) & embedded video don't load. The galleries just show a wait cursor, & the video shows as a black window with no usual static content,play button, etc. There are no error messages or any indication at all what may be blocking them, except that if I disable the NS extension completely (not just "Allow Scripts Globally") they do work(They work with Chromium also). I've fiddled with options etc. all day but I'm completely stuck now. Here's a few example addresses:
