Add me.  It has been my observation that of the six major ECMAScript 
implementations in web browsers that I tested so far¹, it currently provides 
the most complete support for features specified in ECMAScript Edition 5(.1) 
(2009/2011), which is one reason why I used it as a primary reference 
implementation for creating the test cases for the comparison of features.  
The other reason is that Chromium/Chrome has become my primary Web browser 
above Iceweasel/Firefox on the desktop, because of the former's speed and 
versatility (especially regarding HTML5 and CSS). 

Incidentally, the former can probably be attributed to a large degree to V8 
which is one of the few script engines to compile to native machine code 
instead of interpreted byte-code [1a, 1b] (the other I have found to do this 
is SquirrelFish Extreme of recent Apple JavaScriptCore versions [2]).  Which 
– again – points out the importance of distinguishing between 
implementations.

But we are getting off-topic.
