This forum's font looks bad on my new installation

Some forums, including this one, look bad in FireFox on my new installation of Arch. Or more specifically, the main font looks bad.

I had the exact same problem on Fedora a few years ago when I did a new installation. I thought I rememberered that the solution there was to install some Lucida font. But running the command "xlsfonts | grep lucida" gives me the same results on my Fedora and Arch systems.

I installed several font packages which improved other things but not this.

Any ideas? Is anyone similarly afflicted?

Never mind.

Someone suggested I remove these bitmap font packages: xorg-fonts-75dpi xorg-fonts-100dpi

I did and now everything looks beautiful!
