Some https sites not working in ubuntu

Try:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

Then try the web. Is it ok

I tried your command. But the page still not working properly. Its keep loading.

I'm also getting https certificate identity not verified error

It seems to me that these pages are so specifically programmed that they work well only with MS IE.
Quote from their site: "Browser Settings FedNet is best viewed with Microsoft Internet Explorer 5.0 or higher versions, with screen area 1024 x 768 pixels."

You could try different browsers on your Ubuntu system, not only firefox but also chromium, opera,... etc.
Maybe one of these works better.

Have you contacted that bank's help desk with your problem?

Could try an agent switcher to make the site think you are using IE.

@andrew,

I tried with user agent switcher But still its not working.

@Manfred

Yes I called them. But they keep telling me to switch to windows 7

If a web pages depends on non-standard behaviour of MS IE, then there is nothing that can be reasonably done on Ubuntu/firefox side.

Ok thanks for your help @manfred and @andrew

Click "Log on to personal banking" button.. It will load login page on a popup window. As you can see login input fields not appearing in ubuntu which works fine on windows 7
