Website is returning "CSI/tbsd_" and "CSI/_tbnd" errors in browsers
firebug, firefox, google-chrome
Solution
The log entries for `CSI/tbsd_` and `CSI/_tbnd` are not errors but time stamps, which are generated by the Google APIs.
Time stamps can be generated in JavaScript using the `console.timeStamp()` function.
You can also see these time stamp logs on google.com:
Within Firebug they are even displayed as olive lines within the Net panel timeline:
So these log messages are nothing to worry about. They just provide some information for debugging purposes.
Your actual problem related to the error you get in Chrome is caused by a cross-domain request. So the browser is blocking it for security reasons related to the same origin policy. There's a tutorial on "Cross-Origin Resource Sharing" (CORS) at html5rocks.com.

Problem
I have a website that is returning some odd warning messages and errors in both Firefox and Chrome. Firefox returns these errors: ``` GET http://fonts.googleapis.com/css?family=Varela+Round 200 OK 7c8e43d.js (line 18) 13:27:41.46 CSI/tbsd_ 13:27:41.48 CSI/_tbnd ``` Chrome returns this error: ``` XMLHttpRequest cannot load http://fonts.googleapis.com/css?family=Varela+Round. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin is therefore not allowed access. ``` I'm guessing that this problem is related to Google Fonts API and `Access-Control-Allow-Origin` How can I fix the errors for this?
