I created a web application that used many components (Infragistic, ComponentOne and WebGrid). I developed on Windows system with IE, now my customers are using client browser on Linux with Mozilla, firefox, .... It's bad, it seems that nothing work or work not correctly. There are many bugs! It has so many bugs that i think i can not fix all. I wonder that if there is any library (add-in) that support to Mozilla, firefox in order that they work good as IE?
