The guilty FRONT PAGE POST is Daily Kos Radio is LIVE at 9am ET!
I use FireFox and NoScript. NoScript relies on a 'whitelist' that is a P.I.T.A. to create and many sites have their own jscript for functionality. After awhile though it gets better and the tubes get unclogged.
Update: The problem appears to be resolved for the moment.
Those who wish to explore the use of NoScript are invited to follow the link above. It prevents many problems and sites load much faster but the trade off is that most sites require scripts to run more than a basic page. It requires constant tinkering to get right and casual surfers will probably be happier not using it.
dailykos.com and googleapis.com must be enabled for the site to work properly. The rest are for embedded objects.
