When an extension with the proxy permission registered to receive
<all_urls>, the proxy.onRequest callback was not triggered for view-source
URLs. While web content cannot navigate to such URLs, a user opening View
Source could have inadvertently leaked their IP address. This vulnerability
affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
