I recently spent time gushing over the new Maxthon 3 desktop web browser in our Firefox alternatives post earlier this month, and the more I use it, the more impressed I get. It’s incredibly fast, uses very little memory (and with zero memory leak) and has a ton of really useful features built in. It also keeps my laptop running around 20 degrees cooler than Firefox, especially with lots of tabs open. Something to do with CPU load I guess.
