MNFurs web site can not support all the browsers that are on the market. We just don't have the manpower to keep testing and verify that the browsers work.
Saying that we will try to keep these major browser 100% supported and working
IE 8.0
IE 9.0
Firefox Latest From Autoupdate
Chrome Latest From Autoupdate
Safari Latest From Lion
We will also keep these mobile platform working (but not at 100%)
iPad and iPhone latest OS (Webkit)
I hope we can keep webkit browsers at the same level of support but I can not promise it (Hey buy me an Android tablet then I can ;) )
Any other browsers are use at your own risk. I can't promise they will work 100% but if they follow standards it should be close enough to work fine for you.
If you find any bugs, problems, or suggestions please make a new post in the Bugs And Enhancement forum.
