I downloaded WaterFox from their web site (NOT from the repo) and when I
try to run it from inside its folder with the command ./waterfox I get
this error message:

XPCOMGlueLoad error for file "libnspr4.so"

/lib/x86_64-linux-gnu/

"libc.so.6" version 'GLIBC_2.30' not found (required by "libnspr4.so")

Couldn't load XPCOM.

How can I fix this?

The easiest way to install it, is to to get the .deb package.

https://software.opensuse.org//download.html?project=home%3Ahawkeye116477%3Awaterfox&package=waterfox-g4-kpe

Or you could use MX Linux and get it from the repository.

Get which from the repo, WaterFox? or just the library I need?

The link Johnny provided gives you access to either a repo or a .deb for
the Ub version which corresponds to your Mint, which is 20.04. I would
use that, not chase a library.

What I see at the waterfox site is a tar.bz2; what I see from Ub is
wanting users to use snap, which I don't like and which Mint does not
enable in the default.

The advantage of adding the repo is integration w/ the dev updating and
the page has advice about the apt updating and the key business.

So, IF I were wanting to use the Waterfox of hawkeye, I would add the
repo and the key.

I downloaded the tar ball and uncompressed it and the ./waterfox works.
I put it in a folder in .local (for lack of another place) and made a launcher on my desktop. That launcher I put into
~/.local/share/applications. As soon as I did that, waterfox showed on the menu. And it updates automatically for me. No ppa or deb
used. I was surprised. Note my version of Linux below, YMMV.

If you just want to manually make your waterfox.desktop, copy these likes with a text editor. Then put the file in ./local.....
~/.local/waterfox/browser/chrome/icons/default

Thanx for the links. I got the library file (2.31) I needed and
everything is good to go. :-D
