> Web Browsers. There is no modern mainstream browser engine that works in Snow Leopard.
You don't need one. You can either use RDP to a Windows Server running on a lightweight Mini PC (like I do) or use VMWare Fusion in unified mode to have a modern Chrome version seamlessly integrated into your desktop experience.
VMWare Fusion in unified mode is an option I may explore if Firefox Dynasty stops being maintained, but I know the integration wouldn't be seamless enough to satisfy me. Especially given that my web browser is the most used app on my machine, it kind of defeats the purpose of using Mavericks in the first place.
Are you daily driving Snow Leopard? I'd be interested to hear about the experience, if you have anything in particular to share.
