EDIT (Thingol) - Quando vi o título achei que era “Colibris” escrito errado. Mas agora já até instalei o danado no Firefox.
Cooliris now provides you free downloadable extensions that let you preview links with Internet Explorer, Safari, and Firefox without clicking. Installation is quick and easy. Just choose the extension you’d like, click the “Download” button below, and you’re ready to cruise the web in a matter of seconds.
