Though both are Webkit based browsers, Safari urlencodes quotation marks in the URL while Chrome does not.
Therefore I need to distinguish between these two in JS.>
If you are checking the browser use $.browser. But if you are checking feature support (recommended) then use $.support.
You should NOT use $.browser to enable/disable features on the page. Reason being its not dependable and generally just not recommended.
If you need feature support then I recommend modernizr.
