Firefox has announced that it's launching Add-on Collections - the ability for users to bundle extensions together for other users. The company hope that it'll help expose more niche content to more users.

Some sample ones have been created, including a "Web Developer's Toolkit" and a "Traveler's Pack", but users can make their own too - selecting addons, then giving the collection a name.

You can also subscribe to a collection via RSS, getting a notification when new extensions are added to it, as well as sharing by email. Check the video above for more details.
