In one of my previous posts i was writing about very annoying Mozilla Thunderbird behavior regarding SSL certificates. Fortunately some guy has posted an link on the corresponding Bugzilla page for the solution. The solution is a great extension made by Andrew Lucking. It adds the ‘don’t warn me about this certificate in this domain’ checkbox and settings panel where we can control what certificates are overridden. It also allows to remember users choice for expired certs. What can i say - it is simply perfect. Thanks Andrew.
