Often we need to deal with our browsers getting stuck or not working for one reason or the other. There was no way to reset your browser to its defaults settings without losing your bookmarks, passwords, cookies and form data.

Now latest beta version of Firefox 13 is coming with a new feature called Reset Firefox which reset your browser to its defaults settings by creating a new profile and still keeping bookmarks, passwords, cookies and form data intact.
