The Bugbug bot thinks this bug should belong to the 'Core::Graphics: Text' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Let me clarify that this only happens with the flatpak version for me. It does not with firefox from the debian repos (firefox ESR)

[Jonathan Kew [:jfkthame]]

Note that (as I understand it) the flatpak system essentially runs the application in a separate environment that does not share the "host" system's font configuration, so the behavior may indeed be different. I suspect that in the flatpak environment, there's a bitmap Helvetica font present (or another legacy X11 bitmap font that is configured to act as a substitute for Helvetica), and that's what is appearing here. Bitmap fonts don't get antialiased.

This is a dupe of bug 1621915, I think.
