Hi, here is an explanation of the icons in the Site Identity button - [[How do I tell if my connection to a website is secure?]]. ''If your question is resolved by this or another answer, please take a minute to let us know. Thank you.''

If there is mixed passive content (e.g. images) then Firefox shows a padlock with an exclamation mark instead of "[[Site Identity Button|Site Identity Button]]" (globe/padlock) at the left end of the location/address bar. You can check the Web Console (Firefox menu button or Tools > Web Developer) for messages referring to mixed to see what content this is about. *https://developer.mozilla.org/Tools/Web_Console See also: *https://support.mozilla.org/kb/how-does-content-isnt-secure-affect-my-safety *https://developer.mozilla.org/Security/MixedContent
