Feeling kind of dumb, but I did figure it out so I thought it was worth sharing my embarrassment in case it helps somebody else…
Following the news that Mobile Firefox is going to start allowing desktop plugins(!)

I finally got off my butt and installed Firefox as my default browser.
Buuuut… Voyager was still opening links in Chrome, even though Firefox is the new default. Restarted the phone, no dice, then it hit me…
“Dummy, you installed the web app in Chrome…”
Uninstalled the web app, re-installed from Firefox, now all the links open in Firefox.
Admit your mistakes, learn from them, share them with others. ;)
If you’re on android, get it via Obtanium. You get updates as they’re released on GitHub.
FWIW, the PWA on Fennec (Firefox fork) seems to run much better on v1.91-v1.92, and I get my plugins (like uBlock Origin, LanguageTool, etc.)
Edit: nvm lol it ended up slowing down again :(
I get inconsistent performance on Firefox. Sometimes it is smooth and fast. Other times it is laggy
