I'm not sure what you mean; I just tested and all of the examples seem to work in Firefox. Many of them rely on features that have come out within the last couple years, but there's a big difference between "modern" and "Chrome-only".

Some of them are using webkit prefixes, and those only. So it's easy to think they won't work everywhere.

But some of those have been added as standard (with the webkit prefix for all browsers), like explained here: https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-lin...

Which of course is a consequence of it being widely used before it was a standard forcing other browsers to adopt..
