Firefox webpage printing delay
I tried asking this about 2 weeks ago but never got an answer. My computer is running Mac OS Sierra 10.12.6, and for the past month and a half there has been a loooooong printer delay in printing anything from the Internet. It takes anywhere from 45 seconds to a minute for a printer dialogue box to appear after I press a Print icon on Amazon, Ebay, PayPal, and anywhere else. Once it appears I can print just fine, but that delay is getting to be tiresome. I've attempted the "Fix Printing Delays" suggestions in the Mozilla Help area, but nothing I do there has any effect. It's definitely a browser issue, because with the exception of PayPal I can print easily if I use Safari, with no delays. I'd switch over to Safari just to save myself the headache, but PayPal won't print mailing labels on Safari now (security issues with Flash, evidently). Anyone know what's going on here?
