I've seen double posts before but not like this one
You have a few errors with text styling tags that would be easy to fix - http://validator.w3.org/check?verbos...%2Fevents.html
You should not style your content by adding markup, the <br /> tag is for making a line break in text, not for making a space. Add a margin from your CSS instead.
The p text on the left has font-size 18px/14px and line-height 20px/16px
The p text on the right has font-size 12px and line-height 18px
In FF9 those text look like they should according to how you've styled them.
