A community of creators

The add-ons listed here are created by thousands of developers and theme designers from all over the world, ranging from individual hobbyists to large corporations. Some add-ons listed on AMO have been automatically published and may be subject to review by a team of editors once publicly listed.

Get involved

Mozilla is a non-profit champion of the Internet, we build Firefox to help keep it healthy, open and accessible. Add-ons support user choice and customisation in Firefox, and you can contribute in the following ways:

• Make your own add-on. We provide free hosting and update services and can help you reach a large audience of users.
• Help improve this web site. It's open source, and you can file bugs and submit patches. You can get started with a good first bug or view all open issues for AMO’s server and frontend on Github.

If you want to contribute but are not quite as technical, there are still ways to help:

• Participate in our forum.
• Leave feedback for your favourite add-ons. Add-on authors are more likely to improve their add-ons and create new ones when they know people appreciate their work.
• Tell your friends and family that Firefox is a fast, secure browser that protects their privacy, and they can use add-ons to make it their own!
