Opera
Opera’s the other open source web browser and, though it’s been around forever, it only commands around 1% of the browser audience. It’s also the browser that comes pre-loaded with your Wii game system.
PROS: Opera is super fast, has tons of add-ons and is practically virus proof. If you’re visiting the deep, dark corner of the web, this is definitely the browser you want to use. It’s long been a favorite of bit torrent fanatics.
CONS: Anyone who uses your computer will assume you’re spending lots of time visiting the deep, dark corners of the web.
