Ask HN: Did HN's the default font size change?

It has always been 10pt.

I thought the same thing the other week, but it just turned out my zoom was reset. I use 150% zoom on HN, way way improves the readability.

Maybe your firefox add-on stopped working? That just happened to me in the last week or so. I used NoSquint and have now moved to Zoom Page: https://addons.mozilla.org/en-US/firefox/addon/zoom-page/
