Fire Drag oleh Eric Tsang

This simple add-on allows users to drag:

• texts: search in foreground/background tabs
• links: open in foreground/background tabs
• images: open in foreground/background tabs
• customize the search engine
• disable fire-drag on some websites

PS: Need to reload webpages after the installation
