Revision Content

When you install an add-on, Firefox checks that it has been verified or "signed" before proceeding. Unsigned add-ons have not yet been reviewed by Mozilla and might cause security issues. If an add-on is unsigned, Firefox will display a warning message and prevent the add-on from installing.

Add-ons signing targets only malware and browser hijacking. It does not control or censor the content that you choose to see.

Why do add-ons need to be verified?

Add-ons that change your browser's settings without your consent or steal your information have become increasingly common. In order to protect you against these attacks, developers must follow guidelines to ensure that their add-ons are safe before Mozilla signs them.

Developers: Learn more about add-ons signing guidelines at Mozilla Developer Network.

Where can I find signed add-ons?

All add-ons hosted on addons.mozilla.org are reviewed and signed before they are listed.

Add-ons hosted on other sites may or may not be signed by Mozilla. Firefox allows you to install add-ons from other sites, as long as they follow the add-on safety guidelines.
