The pop-up blocker tries to block unrequested pop-ups. Pop-ups opened by user action like a mouse click are considered requested, so they won't be blocked.

You can prevent all pop-ups from opening by setting dom.popup_allowed_events to an empty value in about:config. This will also block requested pop-ups, links that would normally open in a new tab because of the target="_blank" attribute, and the file picker for file uploads.

Bug 565104 covers pop-ups opening in response to clicks in general.
Bug 675574 covers multiple pop-ups in response to a single click.
