The only extension I use in Opera is Meme smileys: https://addons.opera.com/addons/extensions/details/meme-smileys/1.9/ https://addons.opera.com/addons/extensions/details/meme-smil... Anyway, the only extension I've ever really wanted for Opera, is Firebug. The lack of a good debugging tool has long been a good drawback, and even though Opera now has Dragonfly, it still doesn't feel as good as Firebug.
