Social widgets get get pretty deeply embedded into sites, which means sometimes Privacyfix fights with content.
The easiest way to overcome this is to "whitelist" the site so that blocking is turned off when you are on that site (but stays on everywhere else). Here's how to do this:
Chrome and Firefox: Click on the Privacyfix icon, which is either 15 little orange and green dots, or the "Fix" logo. Click the button that says "Allow social widgets" to whitelist the site.
If that doesn't work, go back through the Privacyfix setup again and turn of social widget blocking completely on the Facebook and Google tabs.
Internet Explorer: Click on the blue circle-slash icon in your URL bar when on the page with interference. This will show you how to lift tracking protection when on that site.
If Privacyfix is interfering with just parts of games, like tokens and community features, that may be because these services are operated by ad trackers. Go back through the Privacyfix setup and turn off the ad-tracking blocker.
