Unsafe Javascript log messages

Question

My console.log has lots of log messages like this:
Unsafe JavaScript attempt to access frame with URL http://www.ebay.com/ from frame with URL http://my.ebay.com/ws/eBayISAPI.dll?MfcISAPICommand=getFavoriteNav. Domains must match.
In many cases the domains really are unrelated; for instance, www.versiontracker.com tries to access img.mediaplex.com, and I suspect these are related to advertising banners.
Are these causing these pages to misbehave in Safari? Is this a security precaution that other browsers don't perform? Should web site designers be fixing their sites so that they need to link between domains? Notice that in the case of eBay, they're just different ebay.com servers.

Hi Barry,
That doesn't seem related to this issue, it's not about a log message from Safari, it's about a message that a particular web site sends on their page.
i did not know one way or the other, do you maybe have a ScamBlocker with
your IP, maybe Earthlink,i have them & i get javascript errors at some sites,
In fact, I'm kind of suspicious of the answer on that page. They say that the web site determines what country you're in by the browser language, but I think most sites actually do this by looking at your IP and matching it against geographic IP assignments (this isn't completely accurate, but it's what many sites do anyway).
I do not really know much about this & how it is done, only that there is no such thing as anonymity on the web.
Hope someone else chimes in with more info & helps you out.If i see any thing that seems related, i'll post back.
good luck, Eme:)
