Firefox 4.0 and 4.0.1 can NOT handle multiple user certificates for a secure site (Firefox 2.x.y and 3.x.y CAN!!!)
When you access a secure site with a user certificate Firefox 4.0 and 4.0.1, fail and the server says:
Secure Connection Failed An error occurred during a connection to www...com (Error code: ssl_error_renegotiation_not_allowed) The page you are trying to view can not be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.
The problem is not the site, Firefox 3.x.y works perfect!, it ask the user for the Master Password and then to select which one of the certificates must be used (also ask if this decision will be permanent until Firefox Exit, this allow the user NOT to answer this certificate question every time a negotiation start with the server).
This is obviously a BUG (an awful one), because security should be a priority (if not, you can use Microsoft Explorer)

No, it is not a bug, but it is a fixed bug about a security issue that should fixed on web servers. Firefox 4 doesn't allow this anymore.
See:
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.
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.

Thanks!!!, I see, there is a problem with the old SSL/TLS protocol version that allow a man in the middle attack if renegotiation is active, is not a problem managing the certificates.
thank you again.
You're welcome
So......how do I -FIX- this? my bank won't let me see my account information anymore because of this $%#@ing problem!
On the about:config page, at the pref security.ssl.renego_unrestricted_hosts you can make a double-click and type the web adresses separate by commas (www.adress1.com,www.adress2.fr,...) you want to allow. I've tested it and it works.
