Getting this XMLHttpRequest error since updating today

Before updating this was fine, Now I get this error everytime I focus on a in input:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/

Any idea whats going on? The app seems to be working fine in Chrome apart from this and all the subsequent warnings I get in the console.

GET http://nikkomsgchannel/e?006b005f005e005a004c0045001b0027005000530058002200…5c005b005c00440062002200570040005b0078002a0050005a005200560058002d00280054
