Thanks Steven, I had to take care of a couple other things first.
I did try it on another one of my test sites and it did update like you said. I really like the responsive design now! However, my images are not scaling when reducing the browser window size..?
Also, for some reason if I login as anything less than an Admin, I am unable to access the Connections manager. Did the update change permissions or something? Yes I did check and update the User Roles.
As for the site with the Firefox 21 fudging the CSS, I will have to get back to you tomorrow on.
Thanks for all your help!
