Note* This will only really be different for Windows/Linux users where font-aliasing isn’t a standard feature (like the mac);
but seeing Windows is 95% of the market it’s worth it.

text-shadow: 0px 0px 1px rgba(0,0,0,0);

text-shadow:0 0 1px rgba(0, 0, 0, 0.9);
  /* ffox will simplify the original to text-shadow:0 0 1px #000; */

text-rendering: optimizeLegibility;

* Looks crappy below 16px – Faux works where text-shadow + rgba works*

* Mozilla text-rendering is disabled below 20px *

* Some examples may only work in Nightlys *

Mozilla Notes:

• Firefox automatically uses ligatures on text 20px or larger.
• The 20px threshold value of the auto keyword can be changed by editing about:config
  browser.display.auto_quality_min_font_size
• Not supported on Mac OS, behaves always similar to optimizeLegibility.
