Using Firefox for years on MAC. Since upgrading to 108.0.1 printing no longer works. PDF using either printer icon on page or Apple& P keys, get waiting circle saying "preparing...) running indefinitely, can get out only by escape key. Same page can be instantly downloaded and printed outside Firefox, or printed on Safari. I have rebooted system to no avail. Since problem coincided with update to this update I am treating it as a bug in version. MAC OS is 10.13.6 High Sierra and exhibiting no other issues.
