I am having an issue with the Mozilla Firefox which is not working properly while i am trying to manage my banking account online. When i am visiting the banking site at that time it is throwing the error "Server does not support RFC 5746, see CVE-2009-3555". I am unable to login to my account. So if you are having any solution then please let me know the the same.

This message is generated by the Firefox to aware the Server that there configuration is not working with the Mozilla Firefox and that is why throwing the error with the same so if you are also getting the same issue then i will advise you to check the page after some time and you will get it working Web URL.

If i am not wrong then you might be using the Mozilla Firefox version 3.6 which is inbuilt with the feature that check the configuration of the server which you are visiting and if it is not proper then displaying the error message in the error console. To check the error console go to the tools menu and then to the "Error Console"

The site which you are trying to use might be running with the JavaApplet and the browser is not having the Java feature on that is why you are getting the issue with the same. If you wanted to work with the issue then i will advise you to enable the Java in the Firefox browser and see whether it is working for you or not.

Yes that's true if the browser of yours is not supporting the Java environment then it is obvious to get the message like this. To get rid of this you have to go with the enabling of the Java in the Mozilla Firefox browser of yours. Just go through the below given step and work with the same.

Start Mozilla Firefox
Go to Edit menu
Select the Preferences
Click on Advance
Select "Enable Java"
Thats it!!!!!!

If nothing is working for you then it is better to report about this error to the developer of the browser that is Mozilla. As they are the developer and they might be aware of this issue. So if you wanted to get rid of the same then contact the Mozilla and see what help you are getting from there. Also update the same here.
