Running firefox, I noticed that google was to my eye noticeably fuzzier than with Mozilla. The two attachments show mozilla and firefox rendering the same page with the same font options (This was directly after profile migration from Mozilla => FireFox) Note with xmag that the pixels are not the same, which I would have expected. My *guess* here is that the FireFox gecko is asking for the fonts at a non-integral size, causing fuzziness. Another possibility is that it is just asking for the font at a different size that doesn't render as well. But note the double-sided fuzz on the left stroke of the 'R' - that shouldn't happen with our default font hinting algorithms.

Any different with PANGO enabled?
This is whatever is the default for the FC3 RPMS. I don't know if Pango is enabled in both, neither, or one and not the other.
Check your versions, because pango was enabled by default for a short while, then disabled by default. The latest are disabled by default, but you can enable with MOZ_ENABLE_PANGO=1. We plan on doing FC updates real soon of both firefox and thunderbird that enables pango by default while fixing several other bugs.
$ rpm -q firefox mozilla firefox-0.10.1-1.0PR1.20 mozilla-1.7.3-17 The same difference and same fuzzy fonts in firefox persist when I run firefox with MOZ_ENABLE_PANGO=1.
There shouldn't be any difference between the two. Are you sure that you're default font size in Firefox isn't some random zoomed size? (ctrl-0 will restore it to the default.)
If you look closely at the 'G' in AGP you'll see that they are actually picking up different fonts ... Luxi Sans for Mozilla and some Helvetica clone (Nimbus Sans, Arial, whatever) for Firefox. Since I have my XP partition's fonts in my font path and the page specifies 'font-family:arial,sans-serif' it looks like Firefox is behaving correctly, and Mozilla incorrectly.
