Fields are black-on-black on Firefox w/ dark theme

Text in any textbox is black-on-black with any dark theme. This makes it nearly impossible to actually use the options page.

What OS, browser and theme are you using? That’s not how it looks normally

[JakeMerdichAMD]

Win10 20H2, Firefox 89.0.1, and official 'Dark' theme. Also repros with other dark themes like 'Arc Dark Theme', so if it's a theme issue, it's not just a bug on a single theme. Haven't tried different OSs or a clean profile yet.

Found a key thing to repro: the windows "default app mode" has to be light to repro this (settings->personalization->colors->Choose you default app mode). Setting the default app mode to dark makes this issue go away.

Seeing this too:

Firefox with dark theme, running on Arch Linux with the default GTK theme (Adwaita). 👉 I think the problem comes from using a dark skin for the Firefox UI, while having a "bright" desktop theme enabled.

This likely because I load the Firefox’ theme directly and it affects the fields only partially. I need to see if there's some class that should be added to the form to catch more styles.
