Top 6 Web Browsers You Probably Haven’t Heard Of

Swiftfox

Swiftfox is an optimized build of Firefox that’s faster and more cutting edge than the regular Firefox distribution. It works with Firefox plugins, making it remarkably extensible. The overall user interface is similar to Firefox, but is a bit more minimalist and clutter-free. Most other features are in line with what Firefox has to offer.
Why you should consider it: If you love Firefox but want something faster and lighter, then Swiftfox is your best bet.
Current release version: 3.5.6
Operating systems supported: Linux

Stainless

Stainless is a browser created in response to Google Chrome. It utilizes multi-processing architecture like Chrome (which, at the time of inception, wasn’t available for OS X), but also has some excellent features not found in other browsers. One of the most interesting features is the ability to log into one website using two different accounts in separate tabs.
Why you should consider it: The ability to log into a site with different credentials in different tabs makes this an excellent option for many. It’s especially useful if you have, say, work-related Gmail accounts and personal Gmail accounts.
Current release version: 0.7.5
Operating systems supported: OS X Leopard and Snow Leopard.

OmniWeb

OmniWeb is a WebKit browser created by the same people who created OmniGraffle and OmniOutliner. It aims to be fun and easy to use (like other Omni products) and shares a similar user interface. It has all the standard browser features we’ve come to expect (including tabbed browsing, bookmarks, and ad blocking), but also includes Workspaces, which lets you save browsing sessions to open later and includes an auto-save option and a built-in RSS reader.
Why you should consider it: For Mac users who want a browser that’s efficient and easy to use, OmniWeb might be just what you’re looking for. It’s appropriate for power users too, and the Workspaces feature is especially handy.
Current release version: 5.0.1
Operating systems supported: Mac OS X 10.4.8 or newer

Maxthon

Why you should consider it: If you want a customizable browser, Maxthon might be what you’re looking for; it’s built specifically for power users. Between plugins, skins, filter packs, and other customizable features, it truly lets you personalize your browsing experience. For parents concerned about their children’s’ activities online, the filters for blocking content can be reassuring.
Current release version: 2.5.11 (the Classic Version is also available: 1.6.5)
Operating systems supported: Windows

Lunascape

Lunascape is the world’s first and only triple engine browser. That’s right: it’s a hybrid browser that runs on Gecko, Trident, and WebKit. It supports plugins and add-ons from Firefox, Internet Explorer, as well as their own plugin platform. It’s touted to be faster and lighter than many other browser options.
Why you should consider it: If you find yourself constantly switching back and forth between browsers (either for cross-browser testing of web designs or because of add-ons available only to Firefox or Internet Explorer), Lunascape is a perfect fit for you.
Current release version: 6.0.1
Operating systems supported: Windows

Flock

Flock is probably better known than many of the other browsers above, especially if you’re a social media addict. Flock was created specifically to make managing your social media activities easier from within your browser.
Flock focuses on staying connected through social media by making sharing and publishing things easier. It integrates directly with Facebook, Gmail, Digg, YouTube, MySpace, Flickr, Twitter, WordPress, Blogger, Delicious, Bebo, TypePad, Picasa, and more. Special features include a People sidebar, a Media bar (to browse photos and videos from your favorite sites), a built-in feed reader, a photo uploader, a blog editor, and more. There are also extensions and custom themes available for download.
