When printing invoices from ebay I use pre printed paper and with Win 10 and Firefox v 66.05 64bit When changing the header/footer to align the print with the paper it is measured in INCHES - In the UK and EU/Canada/Australia etc we use the metric system so how do we change this to mm.

You can change the measurement units by doing the following:

  1. Type about:config in the Firefox address bar
  2. Bypass the security warning (yes, we will be careful)
  3. Search for print_paper_size_unit

Now you should see a list of each printer that you have installed on your system. To change the unit of measurement that is used, change the values from 0 (inches) to 1 (metric).

You will need to restart Firefox for the changes to be applied fully.

Hope this helps.
