Status: RESOLVED DUPLICATE of bug 323962

From https://launchpad.net/distros/ubuntu/+source/firefox/+bug/19524

Firefox has support for some GNOME integration.  As part of this, it should be possible for Firefox to fall back on the font DPI setting stored inside GConf at /desktop/gnome/font_rendering/dpi.  This defaults to 96, which is what Firefox does as well, but if that's changed then Firefox should change correspondingly.

Reproducible: Always

Steps to Reproduce:
1. Fire up a GNOME desktop.
2. Go into Preferences > Font > Details.  Set the font DPI to 120.
3. Open Firefox.

Actual Results:  
Firefox keeps its own font DPI setting.

Expected Results:  
Firefox sees that GNOME's DPI is at 120 and that it doesn't have an overriding value in layout.css.dpi.  It renders assuming the screen is at 120 DPI.

What's your buildconfig look like? As far as I can tell we try to use that setting as long as it's set: http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/gfx/src/gtk/nsDeviceContextGTK.cpp&rev=1.131&mark=1052-1072#1047

Can you grab the firefox-dbg package and maybe step through that function to see what's going on?
