Diễn đàn hỗ trợ Firefox

I am trying to go to a webpage but I can't the page content correctly as I do on my phone or ipad. Do I have to use Firefox? Is an update needed...my computere says I'm using an updated version. Help! It's important for my son's HS project and deadline is tomorrow.

thank you.

Hi, my 2008 Mac Pro uses OS X El Capitan, version 10.11.6 and I am on Firefox 78.15.0esr, I cannot install the new upgrade. Can I continue using the older version of Firefox even though the sync will not work anymore?
