Ask YC: All things being equal, why would a browser render pages differently?

2 points by lalagrande ↗ HN
I recently reinstalled my operating system, and reinstalled Mozilla Firefox. For all practical purposes, my configuration is exactly what it was two days ago.

However, now I've noticed that margins are a few pixels off in FF3. I'm concerned about designing on this box now, as my CSS might be a few pixels off.

I'm wondering, what might be the cause of this discrepancy?

I really doubt its the margins.

What kind of fonts are on the page? I bet the problem is that you don't have Microsoft fonts installed. (they're not included with Linux distros, for example)

how can you tell that they are "off"? what do you mean by "off" ?
You need to provide more info: what is your O/S, what is your baseline (markup and stylesheet developed/tested first in FF/firebug/Safari vs. IE 6 or 7?), whether your sure this is not an IE 6/7 "feature".
