Ira, in Chrome, but tested Safari, same thing.
Joe, I thought that idea would work! Best idea so far. no go. Did not work, sadly. Disabled Ghostery, buttons still not there. (but will remember that tip!)
What did work (of no help really) is test user logged in FB has buttons Very weird. Something with my primary, main FB user with Canon.
And I say that because I see buttons with other company site.
Still that message is nice to have with Canon.... perplexing!
