Most - if not all - of the sites I have in my subscriptions do not show anything in Story View. This has been happening of late only - a few weeks ago things were smooth.
Using https://? Try switching to http:// and see if it works. If so, it’s due to something in chrome and/or firefox changing.
Jason’s right. If you’re using Newsblur on https, Firefox will block story mode on sites that doesn’t use https. This feature came with the latest update. For users security, Firefox will block http parts of the websites using https.
