Images and CSS Not working in Firefox

Can you take a look at my shop:

http://www.renadamsartshop.com/

Last night, while adding a new product, the site went haywire in my Firefox browser. It is now ignoring CSS and no images are showing up whatsoever in my Firefox browser, but the site looks fine in Opera and IE.

I can't figure it out.

Also, when I log in to the admin area on my Firefox browser, all of the buttons for editing, updating, saving work, etc. are gone. In Opera and IE, everything is fine.

Is it a problem with my browser? I've tried clearing the cache.

using latest firefox , i see no issue with your page .. everything looks just fine

Thank you SO much. I'm also using the latest Firefox, but this tells me that there's something wrong with my local browser or machine. I am glad to hear it doesn't look wonky in someone else's FF.

Anyone else on Firefox want to take a look?

I think I'll end up uninstalling and reinstalling the browser.

looked ok to me too. Page took forever to load on my dialup though ( way over 2 minutes )
