In Firefox 3.6 on Ubuntu 9.10, certain sites seem to use bitmap fonts for any fixed-width fonts, but only at specific zoom levels. This site and other Stack Exchange sites are among the affected sites, and of course the default zoom level is affected. At unaffected zoom levels, I get the expected smooth curvy fonts. How can I make Firefox use the nice curvy smooth fonts at all zoom levels?
Edit: Adding example code for my own reference.
This is code. I want it to look smooth and pretty.
