Helvetica Problems

every time I browse hbr, especially when I get links on twitter, here is what I see (using firefox 3.5.8)

No visible text except the ones in italic. I know there’s something written there because when I tried to highlight it:

It’s kind of annoying because in order for me to read the actual article, I have to print it to pdf. I wonder where the problem lies.. my browser? but it shows other text on the page…i’ve tried to restart..still the same. I haven’t tried other browsers though since I don’t want to be switching browsers just because I want to read HBR blogs.

Hmmm.

Update 1: I tried it on IE..there’s visible text!! what’s up. it’s my browser.

Update 2: I have found the culprit. I installed HELVETICA font the other day and it’s messing up firefox. wth. So i deleted the darn font. Boo. I liked helvetica.
