I have a macbook pro os x 10.7.2 . I have the latest google video plugins ....also I removed and tried reinstalling the plugin for video chat. I have a built in camera. So when I go to google/mail settings, and check my settings, I cant see myself in the video box. If I video chat with someone else, they can see me, but I cant see myself. If I use Safari or google crome for my browser, google video chat works great. I can see myself and see the person I am video chatting with. So, I think it's a problem with the Firefox browser. I am using 8.0.1 thanks Walt
