Many pages that don't work right in Mozilla/NS are actually not working because popups are blocked. Examples include soundblaster.com, nintendo.com and others. In fact, when popups are enabled, these sites work fine again. I think Mozilla should notify the user (maybe by putting a message in the load-progress bar after the page is finished loading) that popups were blocked on any page visited where they were. This lets people know that the page might work better if popups were reenabled temporarily, and at the very least lets people get an idea about where they are blocking popups.
