Created attachment 738274 [details] What happens now -- no video. User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130307023931 Steps to reproduce: I opened a tab for the Linksys WVC80N camera browser interface, same as usual. Actual results: Instead of seeing video on the "View Video" page, nothing happened. Expected results: It should have shown video from the camera. Instead, it showed an empty box. It is confirmed this is a result of the upgrade to FF 20 -- the video still works fine on computers that haven't upgraded.
