Looking up border-radius at caniuse.com doesn't seem to indicate that Firefox has any particular compatibility issues with this particular CSS feature, so the problem might exist somewhere else in your code. By default, browsers will try and figure out what you're trying to do if there are small typos or inaccuracies in your code, but not all browsers do so in the same way. It'd be easier to try and find the root cause if we saw all your HTML and CSS.

Ryan, is there a way to attach it? I can already see that not all of it is displaying properly inline.

Never mind. Got it. Code to follow.

Index.html is followed by all the css and then by about.html and contact.html. Obviously all are in-progress as I'm still working through the course.
