Add IE methods and attributes to moz-firefox

In IECN, we can see that Xinyun's JS about interchange select is invalid in Firefox because removeNode and swapNode are used. Google just found that you can use a custom prototype to correct valid attributes and methods in IE.

The modification scheme is as follows:
