A good program with web filtering will do far more then seen with any addon toolbars. The built in popup blocker seen with IE 8 generally has been all that was needed for most of them besides the type scripted into the sites that roam across the screen.
While checking the 64bit download site visited often since they stay updated in the news there as well I ran right into the Adobe Flash Player "Square" - 64bit Flash Player
posting there with the download links for Adobe. Some additional screens are displayed as well as the download links.
The 64bit Flash even a preview is what everyone has been waiting for. As far as IE 9 beta that will stay on the test drive's copy of 7 not for host drive's OS however since the beta is lacking the main menu bar option and several settings including the option for displaying the Favorites bar which was a bit disappointing but typical for beta releases of anything.
