I understand that emoticons are not showing up in Firefox. In order to make sure it is not just hardware acceleration, after disabling add ons, does this continue to happen? To temporarily allow the mixed content to be displayed: *Click the '''shield icon''' [[Image:Mixed Content Shield]] in the address bar and choose '''Disable Protection on This Page''' from the dropdown menu.<br>[[Image:Fx23MixedContentBlocker|width=500]] To allow insecure content to be displayed in all secure pages, enter '''about:config''' in the address bar and double-click on this preference, to toggle it from true to false: '''security.mixed_content.block_active_content''' You can also use this add-on instead, to toggle the preference: *[https://addons.mozilla.org/firefox/addon/toggle-mixed-active-content/ Toggle Mixed active content] add-on You may want to do this only for the current session, then reset the preference back to "true" and check back with the site to see whether it's been fixed, since this is a global setting that exposes you on all sites, not just the one you care about. Let us know if this helps!
