After removing hash from URL using window.location.hash=\'\' page getting reloaded in firefox.
EDIT
Example:
wwww
From https://developer.mozilla.org/en/DOM/window.location:
Examples
Whenever a property of the location object is modified, a document will be loaded using the URL as if window.location.assign() had been called with the modified URL.
This question I think addresses what you want using jQuery:
