>> So the next question is, anyone running Firefox on Wayland yet? ;)
I run Fedora 22 and tried FF on Wayland. It brought the system to a crawl, but I believe it was using Xwayland and not native. Running it native Wayland is supposed to be nice. I'm hoping my old machine from 2005 will still work great with Wayland. Desktop and simple web stuff worked fine, but it died on cookie clicker.
