Firefox returns "untrusted connection" when attempting to Login to Vodafone. Problem not present when using Safari or IE. Is this a Firefox problem ??
Firefox is my Default Browswer and I have always used Firefox to connect to Vodafone.co.uk, to access my account. Recently I have been presented with Untrusted Connection Warnings and prompted to Add Exception.
I have tried Safari and IE to access my Vodafone account, both work without Untrusted Connection Warnings.
I have reported this to Vodafone Technical Help but they are unaware of any problem, although I am aware of several changes to their Site.
Is this a Mozilla or Vodafone problem and 'what can be done about it' ??

The Vodafone server don't send the required intermediate certificates to build a certificate chain that ends with a built-in root certificate.
- Vodafone (Corporate Services 2009)
- Vodafone (Corporate Domain 2009)
It looks that Vodafone has fixed this on their server, so it should be working now (check the above posted link).
In case you made a permanent exception then you can remove this exception in the Certificate Manager.
- Tools > Options > Advanced > Certificates/Encryption: View Certificates > Servers
