1404663 - about:debugging#tabs actively loads all favicons

Status: NEW

(DevTools :: about:debugging, enhancement, P3)

Description

[Mike Hommey [:glandium]]

STR:
 - Open the browser console
 - Open about:debugging#tabs

Actual result:
 - Observe the browser console filling with requests for favicons.

Expected result:
 - The network is not hit to load favicons.

FWIW, a trick I was using in an addon to avoid hitting the network for favicons was to use a xul:image with validate="never" (doesn't work with webextensions, obviously).

BTW, if some sites in unloaded tabs are behind HTTP authentication and with no favicon, or with a favicon behind the authentication, about:debugging#tabs makes the HTTP auth popup appear.
