In Firefox 42+ you may see a shield icon at the left end of the location/address bar when you are in private browsing mode that some content is blocked. This is a new tracking-protection feature that is enabled by default in a New Private Window. *https://support.mozilla.org/kb/tracking-protection-firefox *https://support.mozilla.org/kb/control-center-site-privacy-and-security-firefox You can disable this feature in "Options/Preferences > Privacy". *Options/Preferences > Privacy: "Use Tracking Protection in Private Windows" ----- You can see what items are blocked in the Web Console (Firefox menu button or Tools > Web Developer). Messages about items that are blocked by Tracking Protection have a red security bar next to it. *https://developer.mozilla.org/Tools/Web_Console <pre><nowiki>The resource at "https://cdn.api.twitter.com/1/urls/count.json?callback=jQuery1113013437340930383423_1447025264067&url=http%3A%2F%2Ffootballmanagerspain.wordpress.com%2F2015%2F11%2F05%2Ftop-10-mc-wonderkids%2F&_=1447025264068" was blocked because tracking protection is enabled.[Learn More] footballmanagerspain.wordpress.com The resource at "https://cdn.api.twitter.com/1/urls/count.json?callback=jQuery1113013437340930383423_1447025264069&url=https%3A%2F%2Ffootballmanagerspain.wordpress.com%2F2015%2F11%2F05%2Ftop-10-mc-wonderkids%2F&_=1447025264070" was blocked because tracking protection is enabled.[Learn More] footballmanagerspain.wordpress.com The resource at "https://graph.facebook.com/?callback=WPCOMSharing.update_facebook_count&ids=https%3A%2F%2Ffootballmanagerspain.wordpress.com%2F2015%2F11%2F05%2Ftop-10-mc-wonderkids%2F&_=1447025264071" was blocked because tracking protection is enabled.[Learn More]</nowiki></pre>

Thank you very much, but I think this option should not be checked, the entire community of wordpress or use the twitter widget you will be failing after the latest update of Firefox. Now works properly, thanks again.

You're welcome You will only be affected by this change if you use Firefox in Private Browsing mode. Note that the New Private Window shows the about:privatebrowsing page with a frame about the state of Tracking Protection. Default settings: *privacy.trackingprotection.enabled = false *privacy.trackingprotection.pbmode.enabled = true

Thanks, you can close the incident.

Thanks cor-el - I was having the problem of the shield showing up even when not in private browsing mode and your information about the default settings in 'about:config' solved my problem.
