UPGRADE TO V3
The chess.com app requires at least iOS 8.0 according to the Apple App Store.
I don't know what the minimum iOS requirement is to access the website via the mobile browser.
Firefox doesnt play nicely with v.3. At least not on a PC.
Firefox works great with v3. I have the regular version on the PC I'm on right now and the Developers Edition on two other machines (2 Windows 7 machines and 1 Windows 10). I can't say some plugins won't give problems, or certain security settings, but I have used Firefox on v3 pretty heavily for 2 years. There was a very short period where there were some menu bugs and I used Chrome until those were fixed, but that is the only major issue, from a browser standpoint.
Can anybody tell me how to upgrade to v3?? Will it work on Apple iPad IOS7??
If anybody has any problems with v3 please discuss. And can chess.com help???
