Share button only visible to admin

The AddToAny plugin is designed to always show the enabled buttons to everyone, so try to pinpoint the root cause of the site issue by temporarily deactivating other plugins and/or switching themes. Be sure to clear/purge your site’s cache(s) as well.

The plugin works fine. The buttons are shown to me as admin and to visitors.
For some strange reason they only don’t appear when I visit my site through a private window on Firefox. I cleared Firefox’s cache but it didn’t solve anything.

Not a problem since it’s working anyway, just a strange minor issue.

Any thoughts?

Firefox’ Private Browsing mode filters out social buttons, etc., so it’s to be expected.
