Sidebar isn't on the right in Chrome

I just finished my very first WordPress website with the Suffusion theme. I am using Firefox as a web browser and everything is just fine. Now I went to check if my site works in Chrome and how it looks. Turns out my sidebar isn’t on the right, but under the main-content. I went to look if the sidebar-width was the problem, but that’s not it.
Can somebody help me get my sidebar to display on the right in Chrome? I would be forever in your debt!
