Not having a problem with opera.

To disable this new thing in Firefox you can go to "Options" "Security" uncheck "Block reported attack sites" and click OK.

Getting it on IE8 also. I ran a search for Jafo from the search box on WC home page, and all the results were blocked, every link on the page.
