Comment (by Thorin):

 Replying to [comment:4 pospeselr]:
 > For mixed content Firefox uses the HTTPS lock icon with a red slash
 through it, while chromium based browsers don't have an icon but instead
 red 'Not Secure' text in the address bar.

 I'm not seeing that. The grey padlock with a red slash is for insecure
 (1st party) pages - e.g http://example.com

 Mixed content: Firefox only blocks insecure active content, not passive
 (by default)
  - `security.mixed_content.block_active_content` = true
  - `security.mixed_content.block_display_content` = false

 For example, using https://www.bennish.net/mixed-content.html - FF default
 (insecure active mixed content) displays a grey padlock with a yellow
 warning (triangle) overlay

 If passive content is also blocked, then
  - FF70+ just a grey padlock is displayed, also the info icon is gone,
 merged into the padlock
  - ESR68, FF69 - a green padlock

 Note: the blocking of subresources has a bug, and the padlock could be
 misleading: but we're only discussing the UX, so it's immaterial
