I can confirm this. In Ubuntu 9.10, font rendering in Firefox was perfectly fine. After 10.4 upgrade, Firefox nolonger renders fonts as specified in gnome's appearance settings. It is like it is doing it's own antialiasing, but ignoring the subpixel smoothing options.
I have attached a screenshot comparing Firefox and Chromium, along with the appearance properties dialog, and character map. In this screenshot, Firefox is rendering fonts incorrectly.
This also seems to affect Thunderbird in Ubuntu 10.4.
