Is there a way to perform a synchronous AJAX query that doesn't freeze the browser? In my opinion synchronous requests are a lot easier to work with in most cases, but the fact that they block other parts of the code from executing is a real killer. Is there a way to get synchronous AJAX without the negative side effects? (And yes, I realize that the term "Synchronous AJAX" is an oxymoron.)

It's supposed to be asynchronous, so the best approach is to design the code to work asynchronously.
