Version 129 is not printing headers and footers, despite manually checking the "print headers and footers" box in the print dialog (and despite making Page Setup visible via about:config). This persists in the preview, when printing to PDFs, and when printing to physical printers. This is new behavior to me since some time in the 128 series (the last time I tried to print a webpage showing the URL and date/time).

I have manually reset all print_h... and print_f... entries to default, but that didn't help either.
