I cannot open PDF files from Firefox for Android

I can't open PDF files from Firefox for Android. When I try to open one, the Google PDF reader opens for half a second in blank and closes. I tried with an open source PDF reader too, PDF Viewer Plus from F-Droid, and when I open a PDF file with this app, the document doesn't load — it stays blank too.

When I try on ProtonMail client and Brave browser both PDF reader apps work.

The Android PDF.js extension works but it isn't optimal.

My device is a Xiaomi Mi A2 and I'm running Android 10 with the latest patch.

Just found that the Nightly version works, but the problem remains in the stable one
