Popup Blocker of Firefox does not work properly.
I turn on the popup blockers for almost 99% of the sites, but this one site (http://www.bongda.com.vn) keep popup this site (http://www.tinthethao.com.vn/photo) almost every single time that I click on any link of it pages. Did not accept any third party cookies including not accepting the cookies from the site mentioned above. Not only this site, I went to DenverPost.com, and the popup window always popped up even that I don't allow it. And it become very annoying.
