When jQuery 1.9 released, then the source map feature was supported by Chrome only. And now the latest version of Firefox 23.0.1, also supports this feature. Find out how to enable source maps in firefox?
You will get this error in Chrome and Firefox only when you have enabled "Source Map" features in browser. Read about how to enable this feature in Chrome and Firefox.
From Official jQuery website,
So when you download jQuery library then you should also download the source map file. For example, if you have downloaded jquery-2.0.3, then you should also download called jquery-2.0.3.min.map.
The only way to fix this error is to place source map file at same location where is your jquery library is. For example, location of jquery-2.0.3.min.map must be where is your jquery-2.0.3.min.js file is.
