Unable to print preview or print consistently in Firefox v90.0.1 (64 bit) on MacOS Catalina 10.15.7 with recent Firefox update. This results in lost data when printing as sections/lines of text disappear when default used, fit to page used, scale used, etc.... in preview... then mirrored (not printed) on printer/paper. Can't trust print layout at this point... causes finnicking with print settings to show data on preview, never sure if it will print this way... need reliable PRINT PREVIEW & PRINT functions... please correct

Hi grant.leclerc, yes, sorry, there is a bug in Firefox 90 with all scaled printing. Whether you change the scale manually (for example, reduce 100% to 70%) or use Fit to page width/Shrink to fit, in either case, content is truncated.

Depending on the page, you could switch to Landscape mode and see whether it will fit without scaling.

A patch has been developed and is in testing in the Nightly version (future Firefox 92) -- it works. Hopefully it will go into beta testing this week (in future Firefox 91). I don't know when it might be released as an interim update for Firefox 90, or whether that will happen.
