I\'m stumped. A client and I are both running Firefox 3.0.12 on XP machines. We view the same page in the same browser on different machines and have different results. Note: Al
Since we can't take a look at the site in our own browsers, here is the process that I would use to try to nail down the issue:
Start removing code blocks piece by piece until the two browsers look the same.
Whichever block of code you last removed that made everything line up perfectly (even if you are missing a chunk from the body), that's near where the culprit is.
Since you've found the culprit, place all of the code back. Start messing around with the fonts first off. Change fonts, sizes, remove text, etc. until you can find a condition under which the browsers are the same. If it's not a font issue, start messing around with other parts of it until you've found the condition that matches it up.
Once you've done that, you will know your issue and you can work around it.
