Reverted Privilege Manager has been disabled

Published: | Categories: Privacy & Security


The Privilege Manager, a JavaScript extension that has been deprecated since Firefox 12, has been disabled. Changing the value of a hidden pref security.enablePrivilege.enable_for_tests to true can test this feature, but of course it’s not recommended. You should find a workaround like an add-on where privileges are actually required.

Since some sites are still using the object for browser detection, the object has been temporarily restored. From now, use an alternative way to detect browsers.
