I know that ZOHO Creator supports the Firefox browser. Indeed I have never had any issues using FF with ZC and it's what I use all the time. I have also seen that Internet Explorer 8 does not have any (to my knowledge) issues with ZC.
Now on to my issue: Many of my users in education, and therefor typically use Apple computers. The Safari browser is not compatible with ZC. Recently at one of my workshops, a Mac user was having all sorts of problems with ZC forms not rending properly and/or experiencing the "never ending submit graphic". After installing FF for Mac, all these problems went away.
ZC Support: What is your official statement on browser compatibility? I'm going to copy whatever statement you reply into my forms to warn my users.
Also, it sure would be nice to have a ZC function to detect browser type and then depending on the output, take some action to suggest downloading FF etc. I suppose JavaScript could do this, but we all know that's not allowed.
