Hi guys, The site recommends Chrome and Firefox claiming they give the best experience. I've been using roll20 for over a year now with various browsers including Firefox, Chrome, Opera and IE. IE is the worst experience having significant incompatibilities. Firefox is second worst because of its poor implementation of javascript and it's lack of a true fullscreen function. Chrome is second best with good performance but poor fullscreen support. Opera, is hands down the best browser for roll20. Why? 1) Performance: Opera and Chrome are the only two browsers that give flawless performance with the advanced features like vision blocking. Firefox stutters when it hits too much vision blocking. 2) Interface: Firefox and Chrome do not offer a true fullscreen mode. When users try to interact with Roll20 on one of those two browsers and their mouse goes too close to the top of the screen the browsers inteface pops up over the page, causing frustration. Opera and IE offer a true full screen interface which requires the user exit the full screen mode to access the browsers interface. This is preferred for web apps like roll20. That's my suggestion based on my experiences. I definately think Opera deserves a mention.
