I've recently discovered this browser and I'm really impressed.
It's called The Pale Moon Project.
So how come it's a good browser and you never heard of it?
It's simple, it's not a stand alone big budget browser, it's an open source project.
In short it's a highly optimized Firefox, and it works like a charm.

A short copy paste from the FAQ:
edit by crev: allowed myself to edit the title because of a typing error (you forgot the "w" letter in browser)Is Pale Moon safe to use?
Absolutely! Pale Moon is built from the Firefox source code that has a large community of developers and security-aware people, next to having seen over a decade of development by now. It includes, among other things, protection against dangerous add-ons, scam sites, automatic checking for updates of add-ons, anti-phishing, anti-malware, password protection (master password), website-identity information in the address bar, and private browsing.
My antivirus software complains that Pale Moon is a trojan or keylogger...
Some Antivirus software is a little too paranoid in their scanning for potentially dangerous programs. It seems scanning with what is called "heuristics" is still something extremely difficult for people to implement properly, and as a result, some AV scanners are rather paranoid whenever a complex piece of optimized software is encountered. Pale Moon has been scanned by several leading and independent software distributors and found to be 100% clean and safe.
