I had this problem with the LastPass browser extension. I proved my theory by disabling LastPass and reloading the site in question - the warnings were gone!

I really didn't want to disable the JavaScript and CSS source maps so I have made the following change below:

Pending an update from the LastPass that addresses the issue, I have temporarily fixed this by changing one of the settings in the Extension settings for LastPass.

I had this setting previously set to On all sites, which was injecting the LastPass code on all sites blindly. With this change you need to right click on the Username/Password box to enable last pass, but on the plus side there are no warnings in the console anymore.

I consider this a temporary workaround until either Google or LastPass fix the issue.

<hr>

EDIT: There is also a checkbox in the settings dialogue for the Console tab itself called Selected context only. Ticking this will remove the warnings and errors from Chrome extensions. Note this setting is not persisted - you'll have to click it each time you open the Dev Tools.

I've just used Chrome Console Filter <code>-chrome-extension</code>. I see everything except chrome-extension output.

blocks|key|605680|text|对我来说，这是McAffee网络顾问浏览器的扩展-删除和消息消失:)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|605681|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For me it was the McAffee Web Advisor Chrome extension - removed and messages gone :)

this worked for me:
<ol>
<li>Find the path to the extensions. Type this in chrome: chrome://version/ . Look for the profile path. this location is where the extensions are saved.
</li>
<li>Open the location with the file explorer. In my case it was something like (AppData\Local\Google\Chrome\User Data\Default\Extensions\hdokiejnpimakedhajhdlcegeplioahd\4.51.0.1_0) The error was with the last pass plugin.
</li>
<li>Create the missing maps. In my case it was: sourcemaps/
</li>
</ol>
Note that i only created the empty maps.

blocks|key|605665|text|我所做的就是禁用我的LastPass扩展(插件)，清除浏览数据，硬重新加载页面，它工作良好。它可能是你的另一个插件|type|unstyled|depth|inlineStyleRanges|entityRanges|data|605666|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

All I did is disable my LastPass extension(plugin), clear browsing data, hard reload the page and it works fine.
It might be another plugin for you

You need to open settings from the debug console

<img src="https://i.stack.imgur.com/mA8zi.png" alt="Open settings console in Chrome">

Then you disable one of chrome's option (They added it recently)

Just refresh the browser and all ready

A week ago i think, I started getting warning messages in my google chrome console. 

<a href="https://i.stack.imgur.com/Aurgz.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Aurgz.png" alt="messages"></a>
Clearing cache doesn't change anything, the messages disappear only in incognito mode.

Any ideas how to get rid of these warnings ?

我想，一周前，我开始在我的google控制台上收到警告信息。​清除缓存不会改变任何事情，消息只在匿名模式下消失。有什么办法消除这些警告吗？
