I am having problem with AdPeriscope on Firefox and/or Internet Explorer....which browsers do you support?

We support Chrome and other webkit based browsers (such as Safari, Opera etc.) currently. That does not mean that the site will not load on other browsers. However, there may be occasional hiccups and rendering issues on other non-webkit based browsers such as Mozilla (aka Firefox) and Internet Explorer. Please bring those to our attention and we will fix them asap. We do highly recommend using Google Chrome, if possible.
