Opening URL in background causes full screen to exit

Question

That's the issue.
While in full screen, loading an URL in a background tab causes Firefox to exit full screen.
I'm wondering if anyone is aware of an add-on that may cause this.
It only occurs in my default profile which has a lot of add-ons. I've tried disabling a few that seem like they could be the obvious culprit, but so far, no luck.

If you are using java client then you can use some java code to call the url and make a get request. Based on the result, you can proceed.
You can use apache commons HttpClient to make http request to URL. OR
URL url = new URL(your url);
URLConnection conn = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line; while ((line = in.readLine()) != null) {
//your business logic
}
