Firefox Popup Blocker
The Firefox popup blocker is a very nice feature. It sits quietly in the background and it does a good job. But there is one annoyance I have with it. Sometimes I actually want to look at a popup, sometimes popups really are legitimate, and sometimes I'm just curious about it and would like to see it - just this one time.
I don't want to allow all popups for the site, all the time. I just want to see this one popup, this one time. There should be an option for this on the popup blocker message that displays at the top of the page whenever Firefox has blocked a popup on that page.
