A browser extension named "Enhanced iFrame Protection", which has this github repo:, gives the user a verbose warning when detecting iframe elements.

The warning is showed to warn the user about a potential security risk. This seems to be a logical feature Mozilla should have.

If implemented, the user should have the ability to e.g. disable/enable iframes in settings in the "Privacy & Security" tab.

Hi people!

@JonThank you!

@AnonymousThat is awesome! It would be awesome if Mozilla combined your plugin with the plugin I referenced to. I would love to be able to block or restrict usage of iFrames in the tab for "Privacy & Security".
