Two-sided Printing is now BACKWARDS
Recently, I noticed Firefox has a new printer dialogue box. When that dialogue box starting showing up, all of my two-sided print jobs are BACKWARDS. The back page is flipped 180 degrees from the front page. WRONG!
As a sanity check, I double-checked with Chrome and Opera. No problem. Double-sided print jobs print as usual (i.e., when you flip the page over in the horizontal direction, the print orientation remains correct).

Somehow, the new Firefox Browser printer dialogue overlay is overriding the HP printer driver. Please fix!

Firefox may have stored the wrong binding setting. To fix it manually:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
(2) In the search box in the page, type or paste duplex and pause while the list is filtered
Firefox should list the print_duplex value for each printer. Printers you have not yet used in the new print experience will have a weird number that is not on this list:
- 0 => print single-sided
- 1 => print double-sided, with long-edge (portrait mode left-right) binding
- 2 => print double-sided, with short-edge (portrait mode top-bottom) binding
To edit a value, double-click the current value to display an editing field. Change it as you wish, then press Enter or click the blue check mark button to save the change.
Does the correction from 2 to 1 work and does it stick?

Brilliant! Worked. Thanks so much.
FWIW I'm told that turning off duplex for one print, then turning it back on, should fix things. I'd be interested to know if that is not the case.
