I use Gentoo and had the same problem, now I have solved it. The issue was that in most systems Helvetica falls back to Arial, which has no problem at all. Now, I had a bitmap font called Helvetica (under 75dpi, we all have it I believe...), and because fc-cache was also registering bitmap fonts, this ugly thing was being used by Firefox in all pages that have Helvetica as default font in their CSS. (for example the page I used for testing: http://www.ubuntu.com/getubuntu/upgrading). Solution: Take 70-no-bitmaps.conf into action. In Gentoo it's activated via te eselect interface, I don't know how it is done in other distros, but I'm sure the file is there. With this rule fc-cache ignores these kind of fonts, leaving the system without a font with the name Helvetica, and so forcing the browser to fall back to something equivalent. Another solution would be to write another rule which states that for every Helvetica-call the Arial font should be used, but this is more complicated in my opinion
