If you've got a development site that uses an self-created SSL certificate to simulate a live, secure environment, you will find a few problems arise when using Firefox 3.0 - this article explains how to solve it.
Firefox 3.0 has many improved security features to help users stay better protected. If your site uses an out of date, or invalid SSL certificate it is possible that you may struggle reaching secure pages in the latest Firefox browser. It is true that Internet Explorer 7 will also warn you about your SSL certificate, but in it's case it provides a nice "Continue anyway" link to allow the secure page(s) to be used.
If the above "Secure Connection Failed" message does appear for you in Firefox 3.0, you will need to click on the "Or you can add an exception..." link at the bottom of the box that appears on the page. This will make a yellow/creamy coloured box appear underneath with two buttons:
- Get me out of here! - This will cancel your request to add an exception and will redirect you to your homepage
- Add Exception - This will open up a new window where an exception can be added.
To add a new exception once the new window has appeared, click on the "Get Certificate" button at the top of the window and then click "Confirm Security Exception". This will then allow you to continue using your secure page(s) as normal and will not ask for this exception to be made again as it will add it with the "Expires" flag set to "indefinate".
