I am using the newest version of Firefox on a Windows 7 premium PC, but when the "Pin" and "Tweet" buttons appear on my hubs for sharing, there is no sign of the "Like" button for Facebook users. Yet there is an empty space where it should be. Is this normal, or has the "like" feature been removed? I am not seeing like buttons when I go to vote on other hubs either. I'd appreciate any advice on this. Thank you.
Thank you everyone for the kind words and advice. I cleared the cache in Firefox and even re-installed it. I have the newest version of Firefox but still the buttons are not present. Weirdly I have been able to see all the bookmark buttons with current IE browser. Perhaps this is just a browser issue.
