Why pay for a browser like Safari or Opera when alls you needs is proggies like PopUpStopper Pro, or AdSubtract. Both have freeware versions as well as relatively inexpensive "Pro" versions. I got my Pro version of PopUpStopper over two years ago and they DO honor free lifetime upgrades and it has an autoupdate feature similar to Norton's "Live Update" feature. This keeps the ad database always current. And with the pro version, you have an "exclude list" which allows you to add to a list, those sites that you will accept popups from. So far, I haven't seen nary a popup that I didn't want or request. AdSubtract goes even one step further and covers all 3 browsers that I use, namely IE6, Netscape 7 and Mozilla, and will not only block popups, but also "Banner Ads" like ones on this board, et. al. But I still allow banners from this forum for ethical reasons including, but not limited to the fact that the dealers support this forum and provide me with my "fixes" when I am experiencing withdrawal. But I haven seen a banner ad from sites like Yahoo or CNN which I visit everyday, and I don't miss them either.
Sorry for being so verbose in this reply, but I feel that both of these products have exceeded my expectations.
