How do I stop this?

Earlier, I asked how to stop webpages from reloading to the point that the screen said "this page has bene reloaded several times due to error" instead of the actual screen content. this happens occasionally on yahoo answers, and ALWAYS happens immediately on gaiaonline.com, wowed.com, and any news article, no matter whether its on NYpost or market watch or any other news site. It NEVER happens on youtube or any other site, though, only these. I was told: "Select Menu > Internet Options.

Go to Security and make sure the right zone is selected (Internet is the default).

Click on the "custom level" button.

Scroll down until you find "Allow Meta Refresh" under Miscellaneous.

Set the option to "disable" (default is enable).

Click ok." Where is "Menu" and all that? I have a Mac OS.
