Like ol' IE does, when visiting a https sites i'd like to interact only with secure information through a secured connection.. couldnt find any setting that enable me to do so, 'cept to exit/block sites.

Chosen solution

enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.mixed_content.block_display_content. double-click it and change its value to true.

hello, firefox will block active mixed content (scripts, css, etc.) on secure pages by default: https://blog.mozilla.org/tanvi/2013/04/10/mixed-content-blocking-enabled-in-firefox-23/

If there is a shield icon to the left of the "Site Identity Button" (globe/padlock) on the location bar then that means that mixed active content is blocked.

If there is mixed passive content (e.g. images) then Firefox shows an exclamation mark instead of "Site Identity Button" (globe/padlock) on the location bar.

Note that Firefox allows mixed passive content by default.

  • security.mixed_content.block_active_content = true
  • security.mixed_content.block_display_content = false

guess the force isnt strong enough sometimes :)

Note that you can see in the Web Console (Firefox/Tools > (Web) Developer) what content is mixed content by searching for mixed.
Matching lines are usually marked as red text.

Same problem here, but setting security.mixed_content.block_display_content to true doesn't seem to change anything; I still get an exclamation mark in a grey triangle sign on some pages. plz halp? :(

You will still get the exclamation mark to make you aware that mixed content is present just like happens with mixed active content that is indicated by a shield icon, but Firefox should now block this passive (display) content.
