Item: Firefox Environment Backup Extension
It’s not something you often think of but a pc is not just a computer, it’s personal computer. Think about it: How easy or difficult would it be to log in and get your work done on a colleague’s machine? We’re not talking about defeating the password, just being a to figure out what is installed, where files are saved and with what defaults the various programs are set.
While I don’t know of a universal “reconfigurator”, I do know of a great utility that will allow you to move you personal browser settings easily from one machine to another, or reinstall them easily on your own: The Firefox Environment Backup Extension.
