Mozilla maintains an open ecosystem for add-ons, which gives developers many choices in how they create, use, and deploy their work. This same openness also provides malicious actors more opportunities as well. While Mozilla can identify and block malicious add-ons discovered through tooling, reviews, or user reports, this is not always enough.
Firefox version 115 introduced Quarantined Domains to protect user privacy and security when we discover significant security issues presented by malicious actors. This feature allows us to prevent attacks by malicious actors targeting specific domains when we have reason to believe there may be malicious add-ons we have not yet discovered. Users can also control this behavior for each add-on in the Add-on Manager (about:addons) starting with Firefox version 116. We will be further improving the UI for users in future releases.
