You can ignore (CSS) errors in the Tools > Error Console. Those errors are only useful if you develop websites and want to check the HTML/CSS and JavaScript code for errors. Most errors are code for other browsers like IE or browsers on other platforms or just typos or the result of bad coding.

Do you have any problems?

This happens when I try to download PDFs from many websites. I'm on a Mac, OS X10.4.1. This seems to have happened fairly recently, say 3 months ago.
