Massive Extender is a Firefox extension that makes it possible to install, uninstall, enable or disable extensions in batches. After you subscribe to add-on collections using the Mozilla Add-on Collector, use check-box in the add-on list below the selected item to specify whether to include the add-on in the batch.
Your selection will be saved for future use until you change it. Batch actions are performed using toolbar under collection's description header. Right-click toolbar header to switch to advanced mode (initially a simple toolbar mode is provided which gives only batch installation options).
