Description Guilherme de Almeida Suckevicz 2020-12-15 17:45:48 UTC 
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.
