Popupblocker can block every popup. Many websites open new windows with ads, when you try to mark text or click something. This add-on will block these and show a really small notification.

Popupblocker: Comprehensive Popup Blocking Firefox Add-on
Popupblocker is a Firefox add-on that keeps your browsing experience clean and focused by preventing unwanted windows and tabs. It features a smart option that limits websites from opening multiple tabs simultaneously. It allows customized settings for a blacklist and whitelist, where specific controls on websites' actions can be set. Notably, Popupblocker eludes detection as a conventional popup blocker on most sites as it goes a step ahead to allow popups, only to block them later.
