I have an iMac and I haven't downloaded any new fonts (that I know of). Both Safari and Firefox display a font that's real skinny and all bunched together. It's definitely readable (it's not symbols or anything) but I have to look close and squint my eyes! It's so annoying! The only new thing I have done is I installed the new Firefox 4. But I don't know why this would affect Safari..? I turned on my computer in Safe Mode to see what would happen and it actually fixed the problem. But once I started it in normal mode again, that font came back. Please help! Sooo frustrated. Thanks!
