isn't there anything to disable in Chrome that would allow the downloads? It seems a little extreme to have to use another browser to be able to download certain file types.
I know, but alas, that's the way browsers are evolving these days. Chrome, in particular, seems in recent years to have taken a more Apple-esque stance, in that, "We don't care what you want, you'll do what we tell you to do."
I frequently run across websites that don't work correctly anymore because of something Google or Mozilla changed in a browser update. Sometimes you can revert something in advanced settings (see chrome://flags in Chrome, or about://config in Firefox), but even if you can, you'll just be playing whack-a-mole every time the browser updates itself ... and they update way too often, IMHO.
Personally, I don't install any browsers on my system -- other than Edge/Internet Explorer (which thanks to Microsoft, you can't get rid of), even though I never use them. I rely instead on portable browsers, and keep auto-update turned off. Every so often I'll download an updated version, but because they're portable I can keep multiple versions around for the times when the newer version balks at something. When that happens, I can drop back to the earlier version or try a different browser. There are only so many hours in a day, and I don't care to waste them troubleshooting browser problems every few weeks.
I also do web design, so it's helpful for me to be able to test webpages in different browsers. Mainly for that reason, I'm currently using portable versions of Firefox 85 and 97, Waterfox 2022.02, Pale Moon 28.7, Chrome 94 and 105, Brave 96, and Opera 85.
You don't need that many, but I'd argue there's a benefit to having perhaps three to choose from, of differing brands and/or versions.
