Description

[Not interested in Mozilla any more]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.10) Gecko/2009042315 Firefox/3.0.10
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.10) Gecko/2009042315 Firefox/3.0.10

If we render the exact same page from Firefox 2 and then from Firefox 3 we get significantly different page lengths. This causes page throws where it didn't before. The font and font size are specified via css but we still get a different line spacing.

We have tried other browsers (Safari on Mac, Opera and Internet Explorer on Windows) and none of them produce this enlarged line spacing.

Reproducible: Always

Steps to Reproduce:
1. Open the webpage.
2. Print to a printer or PDF
Actual Results:  
See that the page breaks are in different locations. This is despite the text size being exactly the same.

Expected Results:  
The page breaks should be in the same place and the line spacing should be the same.

PDFs attached displaying the differences. Please note that these are not simply due to the use of Macintosh style check boxes.
