每当地址栏中的URL更改Firefox JPM时如何获得通知

Question

Is it possible to detect whether an URL changes, while developing Firefox addons using the new SDK/JPM?

It's not exactly hashchange what I want to detect, but any changes to the URL, like ajax request changing search terms or things like that.

Is it a way to do it? Thanks.

I came up with a solution which includes using a combination of MutationObserver and "old location value checking".

Basically I implemented a value check on location.href but using a MutationObserver to detect changes in the DOM, instead of using an interval which would kill the performance and waste some precious milliseconds.

Thanks for the contributions. Hope this helps anyone.
