I upgraded to Firefox 29 but lost my Lightning calendar--how can I recover it?

It seems that now that I have upgraded to the latest version of Firefox, I no longer have a calendar. I tried to add Lightning (the calendar I have been using) and got a message saying that it is not compatible with Firefox 29. So, how can I get a calendar that is compatible and how can I recover the information that I had in my calendar before I upgraded?

hello lchristian14, the lightning calendar addon is only available for thunderbird and seamonkey (it has always been like this, so the last firefox update shouldn't have made a difference in this regard): https://addons.mozilla.org/thunderbird/addon/lightning/versions/
