Does the font look weird on this site?

[Arch Willingham]

One of the main sites we go to daily is our local town's on-line paper (www.chattanoogan.com). I hate to compare it to Windows but with that OS and IE, the pages are very clear. In Firefox (FC6, FC7 and FC8), all of the smaller characters look funky and are very hard to read (look down under the section called "Breaking news" where there are blue letters on a white background). Is it just my setup(s) or does the site look funky to y'all too?

Thanks!
