Needs help with tiny adjustment for FF and IE

Hi again!
I have a tiny position problem in FF and IE on my site.
I use internet explorer 8 and firefox 3.6
This is probably a wordpress issue but it's so weird that it looks perfect in Chrome. I'm starting to love Chrome more and more, oh and yea hate IE more and more haha.

Anyway this is the site: http://noomirapace.org/
In the left sidebar, scroll down to "Most recent posts".
This is where the problem is.

Now compare the placement in Chrome, FF and IE.
In IE and FF the list is aligned more to the left than in Chrome.

I use the same class on that one, as all the other stuff in the sidebar. So yea, most likely a wordpress issue.

Anyone having any ideas on how I can fix this?

Hello Emsan,
That list is invalid. Have a look at unordered lists here (http://www.w3schools.com/html/html_lists.asp).

Oh so then it is wordpress :(

This is the code I added to make them show:
<?php wp_get_archives('type=postbypost&limit=10'); ?>

Is there anyway to tweak that php code? Now it doesn't feel like a html problem anymore hehe
