Firefox JavaScript window.navigate not supported

Wouldn't it be great for us developers, if the world used just one browser. Experienced HTML/JavaScript web developers have learned over time with browsers support certain functionality. I am not going to claim to be a browser difference (HTML, JavaScript, etc.) expert, but I do get to spend more time, than I want to, with these issues.

I recently ran into a problem where a call to window.navigate() on a web page in Firefox was not executing. I learned that I instead needed to use window.location.href = '' instead. Which does also seem to work in other browsers (like IE). I have not fully researched this. If anyone knows the history/reason as to the lack of support for window.navigate in Firefox, please let us know.
