The ability to block pop-up and pop-under ads, integrate with Blogger, and automatically fill out frequently used forms are three new features that Google released today in a new beta version of its popular toolbar for Internet Explorer. Users who download the toolbar into their Internet Explorer software can set it to block all pop-up and pop-under windows or only those from certain sites. The feature blocks advertising and editorial pop-up windows and will probably cause concern among the many major news sites.
