Add-ons Blocking Process
Add-ons enable users to add features to Firefox for a personalized browsing experience. Most add-ons are created with the best intent, providing users with useful and delightful features. However, add-ons can also be used to compromise personal data and security.
When Mozilla becomes aware of add-ons that go against user expectations or otherwise risk user privacy and security, it takes steps to block them from running in Firefox. This may happen proactively, or in response to an abuse report. When an extension is blocked, it is disabled in Firefox and users are not able to override the block.
The following describes Mozilla’s common practices for dealing with add-ons that appear to violate the Add-on Policies. Authoritative information on the conditions for removing or revoking add-ons can be found in the Firefox Add-on Distribution Agreement and the Add-on Policies.
