I get this everyday on my computer. 503 Service Unavailable I do not get this anywhere else
503 Service Unavailable I get this everyday when I browse my blogs and other websites. All these websites can not be down. What is the problem.

Hi!
Does this occur with other browsers?
Thanks!
No only on Firefox.
Are you able to give a couple of examples where this problem always occurs with Firefox but not with other browsers ?
Please provide the address (URL) of examples that are publicly accessible without needing to login.

DOM object detection: objects/methods/collections
As a more reliable indication of a browser's capabilities, scripts can check for the existence of various objects and properties:
if(document.getElementById) = true; // all modern browsers support this method if(document.layers) = false; // this collection identifies Netscape version 4 only if(document.all) = false; // this object works in IE4-8 and emulations thereof
