When I try to log into online banking the security passwords or numbers are not accepted and the error console tells me that the server does not support rfc5746 and tells me to see cve-2009-3555.

See this link for information about 'Renegotiation' (CVE-2009-3555):

You can look at the pref security.ssl.renego_unrestricted_hosts on the about:config page and add the sites that you want to allow to the string value.

Changing that pref to only allow specific web servers is better and safer that allowing global access by setting security.ssl.allow_unrestricted_renego_everywhere__temporarily_available_pref to true.


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
