|If you work at many different places or clean your profile frequently, you'll be hunting and installing extensions more often than necessary. Mass Installer tries to simplify this task:
* Collect the links to all of your favorite extensions (i.e. to the XPIs) in a text file (one URL per line).
* Put this file online or onto some portable media (wherever Firefox can find it).
Now whenever you create a new profile, you'll mainly have to:
* Install Mass Installer.
* Restart Firefox/Thunderbird - now Mass Installer asks you for the file you created and silently installs all listed extensions.
* When all extensions are installed, click OK and launch Firefox/Thunderbird again - there you are.
