Same, except instead of falling in love with Computer Modern, I went "oh hey, XeLaTeX lets me use fonts in a sane way" and started typesetting with modern OpenType fonts instead. So I'd argue there's at least a good chunk of Stockholm syndrome there.

Same. I particularly like Linux Libertine, enough so that I make Firefox use it everywhere, even (especially?) where the page designer wanted sans.

Sadly, mobile Firefox does not support that, so HN on Android is relentlessly sans.

Even if the UI is not exposed, it’s all there in about:config and should work:

browser.display.use_document_fonts = 0

font.name.serif.x-western = Linux Libertine

font.name.sans-serif.x-western = Linux Libertine

Thank you, I had already done that. (Well, "Droid Serif".) For some reason it has no visible effect.

I never got the "Linux Libertine O" fonts to work in my phone. I suspect it doesn't like the file format.
