How to open/use .webbookmark files?

Someone sent me a file in a .webbookmark format. Google isn’t returning anything. The file has a file name with just numbers and letters. It got sent in an email, we don’t know if it started in that format or not. Any way we (pc users) can use/open it? It’s kind of imperative that we open it ASAP and contacting the person is going to take too long. So far all I can find from Google is that it is somehow related to Mac. Any help will be appreciated.

I’m grumpy. If you make a stupid remark beware of my wrath
