Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects

[thomas334]

I try to register via "/register.html" but it seems not to work (I added the ssl certificate).I get a warning in the chrome developer tools console :
"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/.
components.js:21470 opening database signal in version #1.0" ponting to libtextsecure.js:32552 "xhr.open('GET', path, callback ? true : false);"

Do you see any other errors? This alert is just the browser kindly suggesting an asynchronous XHR rather than a synchronous one and doesn't actually block the code from executing as expected.
