Once you have created an extension, share it with the community!
There are a few major sites that list extensions for Mozilla products. The most popular and most important one is the official addons.mozilla.org. Other web portals such as erweiterungen.de list extensions that are available in certain language (such as german e.g.). There is also an Extensions forum at MozillaZine, where many authors announce their extensions and ask for help.
- To submit your extension to addons.mozilla.org, you'll need to create a developer account at https://addons.mozilla.org/developers/ See the  on addons.mozilla.org on this topic.
- There are several active people at Addons Mirror. They may find your extension themselves, especially if you post on the MozillaZine Extensions forum. However, if they miss your extension for some reason, you can announce it yourself in the Announce section.
- If you start a thread about your extension on the Extensions forum, you will probably receive some valuable feedback there.
- To submit your extension to extensionroom.mozdev.org, you'll need to send an e-mail requesting your addition to email@example.com. See the database home page for more information.
After submitting your extension to addons.mozilla.org it might take severals days or weeks until your extension will be reviewed (and approval will be granted). this is important to keep the quaity of the extensions high and prevent the mozilla user community from malware extensions.
