Natao arisiva ity resaka mitohy ity. Mametraha fanontaniana azafady raha mila fanampiana.

Why is Firefox rendering fonts all jagged and blocky, w/no anti-aliasing?

Running FF 29.01 on Windows 7. You can see the image linked below for a comparison of how browsers should render font and how my browser actually renders font. It is not a magnification issue. I've already installed the Anti-Aliasing Tuner extension. I've added the layout.paint_rects_separately boolean as well.

Looks to me like ClearType is disabled. http://www.thewindowsclub.com/disable-font-smoothing-windows

Does this only apply to Firefox? If so did you switch to a different font in Firefox settings?

Try to create a new Boolean pref on the about:config page via the right-click context menu with the name layout.paint_rects_separately and set the value to true and leave hardware acceleration enabled.

From OP:

I've added the layout.paint_rects_separately boolean as well.

Another screenshot to illustrate the issue, if that helps:
