Blurred of soft text until hardware acceleration is turned off
When I have hardware acceleration on in Firefox 4 (Win7 64 bit on a Dell XPS M1330 with a GeForce 8400M GS) the text appears soft and slightly blurred. As soon as I turn "use hardware acceleration where available" off under the Advanced->General preferences dialogue and restart Firefox the problem is solved, but I assume this impacts the performance. Is there anything I can do to fix?

I just had the same problem with every app that use graphic acceleration (java, 3dsmax, Firefox4...). I found a little trick anyway : these applications use your graphic panel manager's parameters in order to render&accelerate.
So open your graphic panel, and try to find the anti-aliasing properties. I got a HD6970 (AMD), and when I disable Morphological Anti-aliasing, everything work perfectly. So it seems to be AA properties. So try to change the application preferences in order to avoid the program overhead it. We haven't all the same GPU or vidcard brand, but I'm aware some graphic processes can deals with performance hit AND rendering troubles.
