It also has a good use of being the toilet of browsers. As in, if you ever are required to temporarily install some pervasive plugin or extension to take a proctored exam or something, Edge is good to use because you know you won't use the that browser for anything you care about and you can protect good browsers from those garbage plugins.

Better to use winget, though. That way you don't even need to bother with Edge's initial setup screens.

As Ftumch said, winget is really the way to go these days. No browser, just:

Terminal > winget install mozilla.firefox > Done.

It's good for viewing PDFs

We wouldn‘t even need it for that if their Windows store versions of browsers weren‘t so terrible.
