What do you mean, I think you said it was also fixed for you. When something is wrong, like I told you, look at the gtk settings in the control center to check both qt and gtk should use the same font, then check the ~/.gtkrc* files it should write, then check the firefox settings, in Edit->Preferences->Fonts->Advanced then dpi or something. Or type about:config in the url bar, and search for browser.display.screen_resolution.
And use "xrdb -q | grep Xft.dpi" to see the dpi used for kde (or any other xft apps). If this setting is not set, the dpi used is the one returned by "xdpyinfo|grep res" -- Menu/dialog font is huge in Firefox since today's update https://launchpad.net/bugs/41453 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
