Ever wander into those pages that will hit you with endless alert windows? The sort that locks up the browser window?
All that I've found that can be done is just end task on Firefox. Unfortunately, that closes ALL of my firefox windows, not just the one that's a problem. Not a big issue, but annoying.
Yeah, I know what you mean. The machine I'm running Norton on just doesn't seem to have pop-ups at all. Either that or I'm not visiting the sorts of sites that you are.
Of course, Norton means that viewing macker's links used to treat me to grannygrot (something to do with the referrer line being scrubbed, triggering his anti-leecher protocol) and some other sites don't work properly.
Oh, 99% of the time I have no popups either. This is one of those rare sites that people create as an annoyance trap. I probably won't see another for quite some time, but I'd rather not have to kill the browser if there's a way to block it.
