Thank you for you plugin!
So far it looks the most complete one.
However, I'm trying to add the like button in the home page.
For some reason it doesn't want to work with Firefox.
Chrome: works perfectly, either I'm logged in to WP and/or Facebook.
Firefox: it keep showing "Recommend - One recommendation. Sign Up to see what your friends recommend.", doesn't matter if I'm logged in Facebook.
I thought it was because I was logged in WP (in this case WP SuperCache doesn't provide cached content), but if I logout from WP and from Facebook when I use Chrome, the like button works as expected (loggin in to Facebook it changes showing the I've liked the button).
If I do the same in WordPress, the like button doesn't change at all.
