Cannot login Safari-Java problem

First of all, you're confusing Java and JavaScript, which are about as unrelated as languages can get. I (and I'm sure others) would appreciate a more descriptive thread title.

Secondly, you can always give Firefox a try: Get Firefox
Note that this URL auto-redirects you to the right part of Mozilla's site.

If that fails, you may have run into a web site that depends on some part of MSIE (Microsoft Internet Explorer), in which case you'll have to resort to one of the following options:

• Running Windows in Boot Camp
• Running Windows in a virtual machine
• Simulating enough of Windows to run MSIE, via Wine

 

Oh... I see. You've run into an issue with Safari's auto session restore feature. To fix this you need to kill the saved state: http://hints.macworld.com/article.php?story=20110722125937252

NOTE: It mentions Lion but works just fine for Mountain Lion too.
