History recovery from backup in Firefox3

Firefox stores the webpage browsing history in the following folder
%APPDATA%\Mozilla\Firefox\Profiles\

In my windows xp machine it was
C:\Documents and Settings\username\Application Data\Mozilla\Firefox\Profiles\ycexgsuz.default

It will be in a file called places.sqlite. For restore I renamed the existing .sqlite with the old one and all the history is available in the new firefox
