as you can see there is no addon as 3.js
To use an addon after copying it to Blenders addon folder, you must activate it first in User Preferences. You find it under: File > User preferences or you hit Ctrl+Alt+U. 

In the Add-on tab you can search for your addon and activate it by ticking the checkbox.
