When I upgrade to new version, if my passwords and other saved forms will be lost?

more options

I have registered in several sites and I have saved all passwords in Firefox itself. Those are very important for me. When I upgrade Firefox to a new version, then my passwords will lost? Or it will all be there in new version also, when I upgrade? Can I take a back up of all this password data? Please give me a reply as soon as possible.

Thank you.
