For Firefox at least, this is probably because you are not using DirectWrite - that in turn is probably because you are not getting D3D10 (you are probably using D3D9 or no hardware acceleration), the usual cause of this is due to out of date drivers or black-listed hardware. You can check what hardware acceleration you get in the graphics section of about:support.

If you are not getting HWA, you can try forcing it on by setting 'layers.acceleration.force-enabled' to true in about:config (I would do that in a throw away profile though because it might crash Firefox; that overrides the black list).

When will users learn to upgrade their drivers properly?

EDIT: For everybody who thinks this should be easy, what's the latest version of the NVIDIA drivers on Windows Update? Is it not "version 257.21 or newer"?


To be fair, I think the better question is when will driver vendors learn to have their drivers update automatically? Checking to see if your drivers are up-to-date and installing new ones is a tedious process, and I shouldn't have to do it just to have a usable machine.

> I shouldn't have to do it just to have a usable machine.

The complaint isn't that Chrome and Firefox don't work.


Yet another technical step that users should learn to do? Computers should work for users, not users for computers. When will operating system manufacturers learn to not make users think (about things they shouldn't have to care about).


As long as users don't explicitly disable windows update, I think this should work fine in the background.


Updated driver. The text is still rendered the same - zigzags instead of lines.

Now about:support shows

So, DirectWrite is on now.


A commenter in my blog suggested to ensure ClearType is enablied in Windows settings - and indeed, I found ClearType disabled. After enabling ClearType the fonts look good in FF and Chrome.

The commenter explained that "IE uses it's own version of Cleartype regardless of system settings, while Firefox and Chrome correctly adhere to your system settings."


Assuming you have 64-bit Windows, install this: http://www.nvidia.com/content/DriverDownload-March2009/confi...
