Unable to Print Labels off Firefox on Zebra printer

[cynic-cards-and-games]

So, I did a refresh on FireFox and it messed things up. I was able to get all my tabs and bookmarks but, My Zebra LP 2844 printer will not print. It will go through and print out a blank. I have to go over to IE to print and I don't want to keep doing that. Any suggestions?

In FF go to Tools>Options>Applications, and scroll down to Portable Document Format (PDF).  Set this to Adobe.
