jquery chrome Error in event handler for runtime.onMessage: TypeError: Cannot read property 'length' of null

Question

I've just started getting the following error in all the pages on my website. This looks like some low level chrome api stuff but I'm not sure why it's suddenly showing it's ugly head?

Error in event handler for runtime.onMessage: TypeError: Cannot read property 'length' of null at topLevelDomainOf (chrome-extension://bfogiafebfohielmmehodmfbbebbbpei/cfg.js:1:2012) at chrome-extension://bfogiafebfohielmmehodmfbbebbbpei/content2.js:1:11080 at null.

Answer 1

The error depends by one chrome extension. Because in the stack trace there is a path with schema chrome-extension://.

Some extension, generally, inject a javascript in every page: if this javascript contains some error, you can view it in console.

In your case the extension bfogiafebfohielmmehodmfbbebbbpei is Keeper (you can see it with a simple search on google of this code).
