Re: A Popup! In Mozilla!

This isn't a normal "popup" in that it doesn't open a new browser window. All they're doing is placing this great animated gif over the middle of the page using absolute positioning in the DIV tag. Notice that it looks like an IE window even in Firefox. Really this is a sneaky trick that is pretty annoying. I think this type of ad placement is going to be hard to block since most of the time absolute positioning images is just part of the normal page and has nothing to do with ads, even though I guess at one time pop-ups were used legitimately almost exclusively. At least this page seems to be thoughtful enough to only display the ad the first time you visit it. Tricky little devils aren't they (and getting trickier all the time).

In Mozilla 1.5 and FireFox 0.9 with the pop-up blocker turned on, I get a pop-up! It's purporting to be an important notice from my Network Administrator - you'll probably recognise it;


Looking at the source of the page, I see that the pop-up is being generated by a <DIV> statement that comes after the closing </html> tag which - I thought - was supposed to indicate the end of the document.

Is a web browser supposed to be able to render code outside the <html></html> tags?

Using IE 6.0.2800.1106, on viewing the source, I find that the DIV statement that followed the closing </html> tag is now the last statement BEFORE the </html> tag. What gives?
