List all the web browsers available with "Links to browser site", include platform...

Genesis gave me an idea for a useful page to add to the Gigarocket blog.. an up to date list of all the browsers we/us/you use daily and for development and testing.

Include reasons why you like it and a link - I will kick off an example, make it easy for me to copy and paste your answers to use in a guide, if you have found an obscure browser, let us know, and, if possible, give it a try and report back.... thanks:

Browser: Google Chromium 

• url: https://www.chromium.org/Home
  
• Reason: Open Source, lite, plugins available for web dev and code inspection tools, good support
  
• Platforms: Win, Mac, *nix, android
  

While this is the development branch of Google's Chrome browser, it's very popular and a very good browser. I have several installed but this one integrates well with other Google services I use.
