Hi I just want know what this error message means
Denying load of chrome-extension://cmbbgcooaabknohabmoaikiakkoignai/jquery.min.map. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.
It means one of your Chrome extensions is using a compressed version of jQuery which contains a sourceMappingURL comment, and the extension's developer is most likely unaware of that.
Source mapping is used for debugging purposes, failing to load a map file won't affect the script's execution.
It is also worth noting that newer versions of jQuery no longer contain the sourceMappingURL comment by default. From the jQuery 1.11 and 2.1 release announcement:
Sourcemap changes
This release does not contain the sourcemap comment in the minified file. Sourcemaps have proven to be a very problematic and puzzling thing to developers, spawning hundreds of confused developers on forums like StackOverflow and causing some to think jQuery itself was broken.
As an user, you can safely ignore that error. The browser will only attempt to load the map file when DevTools is opened (and has the "JS source maps" DevTools setting enabled). If it fails to load the map file, nothing changes.
As a developer, you can remove that error message by either upgrading to the latest jQuery version, or manually remove the sourceMappingURL comment from the compressed file, or, if you want to use source mapping, make the map and uncompressed js files available. See this related thread as well.
