Firefox font woes

I’m trying out Firefox via Flatpak. Most things seem to be working as expected but a couple sites have poorly rendered fonts. This includes Github and Reddit. I went into settings and tried a couple different fonts with no apparent effect. Do I need to reload to view modified fonts?

This is using flatpak version

hbarta@olive:~$ flatpak --version
Flatpak 1.10.7

and with

hbarta@olive:~$ flatpak list

Is this a flatpak or firefox issue? Where should I be seeking a solution?

Edit: Apologies for the typo in the sample screen shot. Probably won’t be my last. :stuck_out_tongue_closed_eyes:

Can’t see how to add an image to the OP so I’ll put it here:
