Ssl error disabled with Firefox 3 on https

Hello

I have an issue with Firefox 3.0.7 to access https sites (works perfectly with Firefox 2.0.0.20, as well as IE7) PC Vista Home Basic
Therefore impossible to access a Hotmail account

This displays an error message:
An error occurred while connecting to live.com.
Secure connection possible because SSL has been disabled.
(Error code: ssl_error_ssl_disabled)

Maybe a track: There is nothing in - Tools / Options / Advanced / Encryption / View Certificates / Authorities

So with version 2.0.0.20 certifying authorities are informed

Thank you in advance for your help

Hello,
go to Tools> Options> Advanced> Encryption, two cases of the "Protocols" are they checked ?

Thank you for the answer

Yes, SSL 3.0 and TLS 1.0 checked
for certificates and choose "select one automatically"
(even if it's there!)

Other proposals for resolution?

The great classics to begin.

Tries already in safe mode in Firefox (without reset) and if it's the same with a new profile (without deleting the existing). Ah, yes! NT 6 ie Vista. What is your anti-virus and your firewall?

Same problem

• In safe mode
• With a different profile

Protection software

• Antivirus: Antivir vira A (Basic)
• Windows Defender
• + More recently (but the problem was already present before)
• Anti-spy: Terminator Antispyware (2.5.5.166)

I recall the following

• In FF 3.0.7 or certificates or authorities who are responsible for the installation and not for access to https sites
• In FF 2.0.0.20 and they are responsible to access https sites possible
