Similarly to what @user2492653 suggested, if all you want is the name of the file like Firefox gives you, then you the split() method, which breaks the string into an array of components, then all you need to do it grab the last index.

var temp = url.split("//");
if(temp.length > 1)
 return temp[temp.length-1] //length-1 since array indexes start at 0

This would basically break C:/fakepath/test.csv into {"C:", "fakepath", "test.csv"}
