All these Urls from the table @daKanga has posted starting with "Follow the arrows" do work for me on Firefox Nightly, Chrome Dev on Android 11 / MIUI 12.5.7 stable.
You might want to try Kiwi, Yandex Alpha on Android (both support full Chrome extensions).
Or download the APK file from Iceweasel (GitHub repository) to expand the collection_id.
Note: The normal Firefox stable release channel is worthless on Android since the Fenix rewrite.
A good idea might be to clear all duolingo.com cookies and then to relogin (with your password which you must remember as the jsession_id cookie will be deleted too)!
But the new browsers (new profile) didn't fix it for ya.

Chrome...
Opera opens the story but neither Firefox, Google or Chrome does and Bing and Duckduckgo try to but just hang.
Edit: as does Edge and Vivaldi ( just downloaded)
What version of Chrome?
Chrome Dev V133.0.x build is able to open them here too.
Are you sure the installed Duolingo app isn't intercepting the calls to the /stories Url?
Well, sounds more like your account is not allowed to directly open the /stories link when you're getting redirected???
But all the other normal path stories do work for you?
I had the same issue for 1-2 years with the /practice-hub and /practice-hub/stories Urls when they took it away from me.
Was only getting redirected to the /learn page.
Can you access it?
I'm not very sure what's going on.
Have you refreshed the Duolingo.com page before?
I had no issue after switching from FR to PT.
But I first connected to duolingo.com to make their server refresh the ACTIVE course (no big deal on your side as you're only using the Portuguese course).
AFAIK it's not necessary to have Duolingo.com open in the first tab...but it shouldn't hurt either.
So...only Opera is working for you.
Sorry to hear that.
