Without knowing which page you have set as your homepage, I can only guess that the page is periodically refreshing content on that page giving you those repeated error messages. You need to post the entire error message for us to help you.

orange Firefox button > Web Developer -> Error Console - or {Ctrl + Shft + J}

Locate that error in the list, right-click that message and select Copy. Then paste that error message unto the Reply box here.
