What does being helpless have to do with anything?

If a behavior makes sense and no one would reasonably not want it (like blocking popups during page unload), why does it need to be an option? Why isn't it just "the way the browser works"? What other "unbreak my browser" options are buried under there?

Nobody has actually mentioned a way to block pop-ups on unload with about:config in the first place. Not having ever seen a popup on unload it may actually already work like this.

The option discussed was forcing new windows into tabs.
