Zoho Writer & Sheet is hit & miss

Zoho Writer & Sheet is hit & miss

I like the idea of using a mobile app, but oftentimes, depending on which computer I use, both Writer and Sheet seems to fail using Firefox 2.0 or 3.0. I'll get a bunch of jumbled text that looks something like the below. I've tried refreshing and things like that to no avail.

What do you suggest? I haven't tried IE, and we would like to use Firefox if possible. Please advise.
