Seems to be a problem on your end. It works fine over here, Firefox, Windows 7.

I ran into this issue as well a while back (using FF)...and I believe what I did to solve it was to download and re-install the Open Sans font from this site...

(You may need to reboot the OS for it to take effect)

The point cost font on GAs doesn't look as it should in Firefox (but looks fine in Chrome & Explorer).
The digit 4 is unrecognizable...
The digits 0,2,3,6,8,9 have holes on top of them.
The digits 5 & 9 look weird in the middle.
Only 1 & 7 look OK.
I'm not using any add-ons/plugins that change the look of the site - it's all vanilla & at default text size.
This isn't a new issue either.
You can see what I'm talking about in here or just expand each of the following images (they're ordered):
