Part of this page - http://www.metoffice.gov.uk/public/weather/forecast/gcwcrzchw - never finishes loading after updating to Firefox 50.1.0. A clean install of the portable version works OK, as does a restore of a backed up v42.x. Updating to the latest beta version doesn't work. Restarting Firefox 50.1.0 or 51.0beta11 (after updating) in safe mode doesn't work. (32 bit versions in all instances, Win 10 Pro) Is there anything I can try to get this page working without a fresh install? It doesn't appear to be an extension problem, so I would prefer not to have to reinstall them all
