Check Your Code
W3C.org (World Wide Web Consortium) in charge of standards and practices and future development of web pages and web browsers make the rules on code. Mozilla Firefox follows these rules.

Please let us know if this solved your issue or if need further assistance.
You can see a special padlock at the left end of the location/address bar.
- a padlock with a strike through means that mixed active content is blocked.
- a padlock with an exclamation mark attached means that mixed passive content (e.g. images) is present, but not blocked.
The shield icon, previously used for mixed active content, is now used for Tracking Protection.

If images are missing then check that you do not block images from some domains.
- you can tap the Alt key or press the F10 key to show the hidden Menu Bar temporarily
Check the permissions for the domain in the currently selected tab in "Tools -> Page Info -> Permissions".
Check "Tools -> Page Info -> Media" for blocked images
- select the first image and use the cursor Down key to scroll through the list
- if an image in the list is grayed and "Block Images from..." has a checkmark then remove this checkmark to unblock images from this domain
You can check these preferences on the about:config page and make sure they have the default value.
- permissions.default.image (1)
- network.http.sendRefererHeader (2)
There is Tracking Protection that can block (wanted) content, so check the location/address bar for special icons. https://support.mozilla.org/en-US/kb/tracking-protection-firefox If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (e.g. Adblock Plus, NoScript, Ghostery, uBlock Origin) always make sure such extensions do not block (wanted) content.
- make sure your extensions and filters are updated to the latest version
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
