If you get the lock with the warning triangle, it usually means there is an HTTP: URL in one of these places:

  • inline images: <img src="http://mylogo.png">
  • CSS: {background-image: url(http://mylogo.png);}
  • site icon: <link rel="icon" type="image/x-icon" href="http://favicon.ico">

If possible, remove the protocol and use a relative link so that if the user loaded the page using HTTPS, the images also will be loaded using HTTPS:

<img src="//mylogo.png">

Here's an old article about that option: https://blog.wikimedia.org/2011/07/19/protocol-relative-urls-enabled-on-test-wikipedia-org/

If you have trouble finding all the mixed content, use Firefox's Web Console. You can open the Web Console in the lower part of the tab using either:

  • "3-bar" menu button > Web Developer > Web Console
  • (menu bar) Tools > Web Developer > Web Console
  • (Windows) Ctrl+Shift+k

Then reload the page in the upper part of the tab and above the messages, type mixed into the filter line to surface the most relevant messages.

Success?
