Why is my input field uneditable?
===

I'm building a web page with many mixed-in libraries: jQuery, Bootstrap, a number of other services' scripts, and so on.  I'm using an earlier (modified) version of the [Really Simple Color Picker](https://github.com/laktek/really-simple-color-picker), and the input control is uneditable, but only in Firefox.  In Chrome, Safari, and Internet Explorer, the field is editable.

I can find nothing in the code that is making the field uneditable.  In Firefox, I can see in the firebug panel that the `.uneditable-input` CSS styles are being applied, but the element itself has no classes, either in the original HTML, the HTML view, or the DOM view.

Some other attributes that seem related in the DOM view are: 

     className ""
     contentEditable "inherit"
     disabled false
     hidden false
     indeterminate false
     readOnly false
     required false


What could make my input uneditable, and why in only one browser?
