I am running FireFox v19.0.2 and I keep having text on pages get a messed up as if clear-type was suddenly turned off... tab out and back in and its fixed... but it comes back and happens often. This only happens in FireFox. I am running Win7 64bit and this is a new issue. How do I fix it? Its driving me nuts....

Try to disable hardware acceleration in Firefox.


Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.
