Viewzi works great in the latest versions of all A-Grade browsers:
While Viewzi will probably work in Internet Explorer 6, we highly recommend that you upgrade your browser version. IE6 debuted in 2001, and is a dinosaur by technological standards. Newer browsers make for reliable development and safer browsing.
Adobe Flash Player version 9 (or greater) is required to experience Viewzi. To get the latest version of Flash player, click here. Heck, you might as well — It's free!
Flash uses a small file called crossdomain.xml that allows Viewzi and other popular sites such as Yahoo!, YouTube, Flickr, and Amazon to load data from public API services.
It has been reported that some firewalls and proxies block crossdomain.xml, which prevents Viewzi from loading data properly. More information on crossdomain.xml:
If you are having trouble using the Flash aspects of Viewzi, try adding all domains ending in "viewzi.com" to your safe list. If you have parental controls enabled on your computer, check to ensure the product you are using does not globally block crossdomain.xml.
