If you’re currently using the spanking new Mozilla Firefox 3, you might notice that when visiting some secure websites - you’ll now get some new error messages that might seem foreign to you.

First of all, this is due to Mozilla’s new implementation of security measures which is a good thing. The Internet is not safe with so many phishing website running rampant and this will help alert the users better.

Some of the more common SSL errors that you’ll encounter are probably;

• ssl_error_bad_cert_domain - which happens when the SSL certificate is registered for a specific domain name but is used for others (shared hosting and such usually falls into this category).
• sec_error_untrusted_issuer / sec_error_ca_cert_invalid - usually happens when the certificate is self-signed.

There’s a whole lot of others SSL errors that Firefox 3 will alert you on and you can refer to them here.

Some of the errors are quite harmless and thus to bypass, one easy solution is to add an exception in Firefox 3. NOTE: Only add an exception if you’re really sure that the site you’re visiting is the actual site you want. Please review the errors properly before adding an exception.

Now, to add an exception - using Meebo.com as an example
(which is a great and safe site btw ) ;

1. Click on the “Or you can add an exception…” link at the bottom of the notice.


2. Click on the “Add an exception” button and a new prompt will appear.


3. Click on the “Get certificate” button, review the certificate if you want and to proceed - click on “Confirm security exception”.

There… you’ve now added an exception and you should be able to access the secure site now.

Cheers~
