The print menu freezes Firefox. I first thought it was my printer and uninstalled and reinstalled both the printer and Firefox, then I realized it also freezes when I try to print to PDF, and just now realized it's already frozen even if I cancel out of the print menu. I don't print from Firefox often, but I just found this problem, I'm not sure if it's related to a recent update. I'm on Windows 10.

Clarification: I "refreshed" Firefox, rather than reinstalled.

If you open the page `about:config` and type in `print_printer`, what is that set to?
