I didn't like you redirecting to Facebook either. That seemed like using a baseball bat for something that needed just a little finesse
As for Yes/No vs Yes/Cancel, you're not the only one that would like that. While it is possible to make a Yes/No popup box with Javascript, it's basically creating a whole dialog box from scratch and could take a bit of work. The "confirm" method I used is the standard way to do that, and it has no way to change the stupid buttons.
Anyways, glad to hear you got it going, and should you need anything, just let us know!
Finally, please consider leaving a rating and review on the Joomla Extension Directory for JFBConnect, or our support. It's certainly not required, but very appreciated!
