The Quarantined Domains feature aims to mitigate potential attacks by malicious actors targeting specific domains, especially in cases where undiscovered malicious add-ons may be present.
Although users can disable this feature by adjusting the “extensions.quarantinedDomains.enabled” setting in the “about:config” section, Mozilla plans to enhance the functionality in future updates. Firefox version 116 is expected to offer users more control over the behaviour of individual add-ons.
