I'm noticing some weird bug in Mozilla (Firefox) I'm not familiar with. Certain pages are loading in with wrong font-size. When these pages load, all font-sizes are bumped up to a larger size. Here's the strange part... It only happens in Mozilla-based browsers and it only happens on pages that are slow to load. Furthermore, if I clicked out of the page and return to it, the font-size is set to normal size as defined in the CSS.

Has anyone come across similar problem? Do you have any suggestions as to how to combat this bug?

FYI, I'm using external stylesheet with all font-size's defined in relative units (em's and %'s).

Thanks in advance,
