I don't know if a Firefox update or new version is doing it or what, but I can't open Weather Channel videos, and assorted other video clips on various websites, and just discovered I can no longer make the link boxes on Photobucket work. I haven't, myself, changed browsers or Add Ons. I have noted that since this started that I have to "allow" Flash to open many things that will still open. Use Win 7 Home Premium, Firefox 42 (per Better Privacy which says it's not compatible with FF42), Yahoo, Zone Alarm firewall, and AdAware Free, and as far as I know the latest version of Flash. I have the usual add-ons in Firefox, but haven't changed or added any since before this all started. I've tried disabling some of them one at a time, such as various blockers, with no improvement. Getting to be VERY frustrating, thanks for any tips or suggestions.
