Bug Description

If I have Ubuntu with Gnome only, no problem.

I installed systemsettings + kdebase-workspace-bin (for configuring fonts in kde4 apps), but when I changed fonts, firefox-3.5 uses the kde4 fonts renderer (which doesn't use subpixel rendering) instead of the gnome renderer. This is the only non-qt4 app which have the problem, it works fine with firefox-3.0.

For me, Shiretoko does not respect subpixel smoothing and hinting set in gnome-appearance-properties (Firefox 3.0 does). FWIW, I have qt4-qtconfig installed.

firefox-3.5:
Installed: 3.5+nobinonly-0ubuntu0.9.04.1

firefox-3.5-gnome-support:
Installed: 3.5+nobinonly-0ubuntu0.9.04.1

The screenshot shows gnome-panel and firefox-3.0 (correct smoothing) and firefox-3.5 (incorrect).

Have got the same problem. But it is incorrect to say that QT don't use subpixel rendering - in fact looks like that after installing KDE systemsettings and kdebase-workspace-bin fonts that are used by the firefox are controlled by KDE system settings, including KDE's ability to do subpixel rendering if properly configured for it. Affected parts of firefox include menu bars, popup menu, bookmarks toolbar and tabs selector, meanwhile page rendered and input boxes still use fonts from gnome-settings.

Looks like this is the duplicate of #379761. The problem is that firefox-3.5 uses ~/.fonts.conf instead of gconfd method to get fonts hinting settings to use. Figured it by changing fonts in KDE system settings one by one from sans to serif typeface and seeing no changes in FireFox. Meanwhile changing fonts hinting settings in KDE changed the FireFox appearence. After bringing KDE's settings for hinting in sync with gnome's firefox became more-or-less the same as it was before installing systemsettings and kdebase-workspace-bin.

From the Design-team and Ubuntu Font Family side, we have bug #621198 which is to ultimately harmonious the font rendering preferences; at the moment it differs between toolkit and some applications (Firefox in particular) are doing their own thing which brings inconsistency to the user interface.
