This is a problem in several Linux's distros, most of them which are "stable" releases, not rolling ones. As difference vs. Windows, Mac, or Android, systems in which you find developers constantly updating and packaging apps for those systems (as .exe files, in app stores, etc), here on Linux you have a thousand systems with different packages, installers, not always updated or the same dependencies... This means that app devs won't waste their lives updating the packages for all distros, only for a few ones (Ubuntu, Fedora, the more popular ones). And Firefox in particular... Well, I don't know why they publish a .tar file when they can publish .deb, .rpm or even .AppImage files.
But, with Firefox, you have two solutions: Install it as a Snap Package, or install it with the .tar file, replacing all the files from /usr/lib/firefox directory with downloaded one, with any of the two options you'll have an updateable Firefox, like on Windows.
About Nvidia drivers, please refer to my https://bbs.deepin.org/post/151191, 390.77 (last stable ones) work perfectly for me.

Thanks for the quick response, I agree, it's 2018 and Linux distros have been using Firefox for quite some time, and it would be nice for them to package it in .deb or .rpm.  So I just went and did the snap route, thanks for your great advice.  Also I appreciate the info on the Nvidia drivers that was very helpful.

Maybe you can try to use this browser  http://browser.nfschina.com/browser/public/

Impossible to install it for non-Chinese users.

This is the english version:  http://browser.nfschina.com/browser/en/public/     

Looks like a nice browser but out dated.  Chrome 55 and flash 24 ??

Try To Download Manually from official site and Install It By Deepin Package Manager. //NEPAL//
