Pencu Ndimabu Firefox

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

My Firefox browser is old, but I can't install new one ex.120 or 115, because I'm not able to work with Terminal. What to do? I do download, but after "unpack" (sorry my English) there is the end of it. I do not know how to install.

My Wife and I are both 75 years old and have huge problems coping with modern computer technology. We have 3 computers with Ubuntu and Firefox. We find that we are able to successfully connect with most of our accounts. With some accounts like Royal Bank, Nextdoor, Koodo, TD Bank, Canadian Government we get in but only get a blank page and cannot go further. Accounts have told us the problem is Firefox and that we need to change to either Chrome or Edge. We have been with Ubuntu and Firefox since 2006, love both and do not want to change.
