Diễn đàn hỗ trợ Firefox

System is Ubuntu 22.04 LTS. Firefox 130.0 is the browser. When printing PDF forms from a website, the printer dialog shows the paper size as US Letter, but it prints as a tiny version of the document.

When I dig deeper into the printer dialog, the page setup is listed as na_letter. When I change it to US Letter, the document will print correctly, but it reverts to na_letter for subsequent print jobs.

The printer is a Brother inkjet, MFC-J985DW. This problem only started recently and the only known changes have been automatic Firefox updates. Any suggestions for a fix?

Help/About Firefox tells me I have - ver 112.0.1 (64-bit)

There is no option to automatically update.

I have downloaded this zip file - firefox-130.0(1).tar.bz2

QUESTION - How do I instal the update  ? - or can I not with my system - as below

Xtra-PC - Turbo 32 × 1 (purchased 2019)

Ubuntu 18.04.6 LTS

Running on 2010 Acer 4741G computer. 4Gb RAM Intel i5 2.27Ghz

Many thanks for any assistance, John, Brisbane Aus
