Portable Firefox For Web Developers, With Pre-Installed Extensions [Windows]
The idea behind it is that a website designer needs to install a LOT of Firefox add-ons and they sometimes don't install all of them even if they are useful simply because Firefox would become bloated and not very usable for browsing.
By using Firefox PDW, you can have a separate Firefox for all these extensions, without the need to install the extensions on your main Firefox installation. Also, since it's portable, it does not require installation and can run from an usb memory stick.
