No wonder Mr. Alpha was puzzled.
I have multiple pop-up protection on my PC, the browser itself, My ZoneAlarm Privacy Suite which is new so that's not the reason I haven't had pop-ups or pop-up bars in FireFox, Ad-Aware's Ad-Watch Pop-up Blocker...
Hey, I wonder if that's it! I didn't have Ad-Watch on when that happened. I'd unloaded it to make some registry changes and didn't load it back up before I went on line again - gulp, a big oops on my part. I don't like leaving that protection off. I'll visit the site again with it ON and see what happens.
Nope, that wasn't it. I got FireFox's pop-up bar this time, for only the second time in my experience - and yes it is like the one in your picture Scarlett.
Something's different, but what?
