Mozilla Add-On collections are curated lists of browser extensions by users or Mozilla. These add-on collections are displayed on the Mozilla website where they can be browsed.
Most of them are themed, Family Organizer or Web Developer's Toolbox for instance, and offer interesting add-ons for specific purposes. Others are not themed but provide access to great add-ons , new add-ons or add-ons sorted by other criteria that users may find interesting.
While it is possible to install an add-on from a collection easily, it is not possible to install them all or multiple at once.
It is either possible to install add-ons individually on the collection's page at the Mozilla website or, after subscribing to them - which requires a Mozilla account - in the subscriptions tab in the add-on manager of the Internet browser.
It feels only natural that collections would have an option to be installed completely or in batch. This option would for instance come handy to add multiple extensions to a new Firefox installation.
Massive Extender is a brand new add-on that adds batch capabilities to the Mozilla Add-On Collector.
The add-on collector needs to be installed for this to work. A user account at the Mozilla website is also required as add-on collections need to be subscribed to, to appear in the subscriptions tab in the add-on manager.
All add-ons of a collection are selected for mass installation and activation by default. It is possible to uncheck some of the add-ons so that they are not installed with the rest of the add-ons.
The number of extensions that will be installed or activated is displayed in the header of the subscription window so that you know in advance how many will be added to the Firefox browser.
A click on the Installation button displays a menu to install or uninstall the selected add-ons or all of them.
Massive Extender makes it easy to install multiple add-ons in one go. It is an excellent companion for users who maintain their own add-on collection at Mozilla and install it regularly on computer systems. The add-on is compatible with all recent versions of the Firefox web browser.
Update: Massive Extender is no longer working. Mozilla killed the Add-on Collector, and since Massive Extender relied on it for its functionality, its author decided to abandon the extension for good.
A comparable extension to install multiple add-ons of Firefox add-on collections at once is not available.Advertisement
