I’m having some major differences in the rendering of text between Chrome and Firefox. Chrome seems to apply some anti-aliasing rules to the text and shrinks it down quite a bit.
I’ve tried playing with -webkit-font-smoothing, letter-spacing and word-spacing but none seem to really have any effect.
See screenshots

color: #C4C4C4;

font-size: 9px;
font-style: normal;
font-variant: normal;
font-weight: normal;

font-family: sans-serif;
font-size: 9px;
font-weight: 400;
font-style: normal;
font-size-adjust: none
color: #C4C4C4;
text-transform: none;
text-decoration: none;
letter-spacing: normal;
word-spacing: 0;
line-height: 11.0833px;
text-align: start;
vertical-align: baseline;
direction: ltr;
Note that the faded text in the background is just an image.. ignore that.
I have a feeling Chrome has a css switch for anti-aliasing rules, but not sure where to look for more info.

For the record, I’m on Ubuntu. Possibly this has an impact ..
Any tips?
Different browsers use different rendering engines that (are meant to) produce different results. This is especially the case with smaller font sizes. There’s generally not a whole lot you can do about it. If the difference is not intended by the browser’s designers, it’s also quite possible that this is a kink that has been worked out on other OSs, but not yours (Ubuntu).
(That said: have you checked your “minimum font size” in Chrome — Preferences > Under the Hood > Customize Fonts… — and Firefox — Preferences > Content?)
