WHY DOES FIREFOX CONTINUE TO DO THIS????
 

We're at Firefox 3 now and ***STILL*** it lets pop-unders through,
such that the next time the browser is opened, I get the damned pop-
under again instead of all my tabs!!!!

Is there no way to stop this pop-under crap????

Moreover, Firefox then ***FORGETS*** about those tabs, and the
"Recently Closed Tabs" Option under "History" is wiped out!

@#$%&!!! Why doesn't Firefox do something about this??? Damned pop-
unders make Firefox forget the tabs that were open from the previous
session, such that even the "recently closed" history disappears!!
