Everyone who has updated to Firefox 3 will very quickly encounter an error message that is not easy to instantly work out how to fix.
When visiting many commonly used sites such as Google, Yahoo, your ISP etc you might be presented with an error screen instead of the site, announcing that the site is using an invalid security certificate, and Firefox 3 will not allow you to bypass it to actually get to the site. Quite mad!
I initially encountered this problem with many sites I use daily. The first was the Firefox Add-Ons site itself. Others included the 1and1 admin login, Google and a few more.
To access such sites again you need to add then to the Certificate Manager exceptions list. To do this you have to go to Tools/Options and then to the Advanced Tab and click on View Certificates. Then navigate to the Servers tab and scroll down through the list of Certificate names until you find the site you cannot access. Select this and then click the Add Exception... button. Then add the server location (the full url of the site/page you are trying to access) and click Get Certificate. It will show details of the Certificate Status and the problem it has with it. Make sure Permanently store this exception is ticked, and then click the Confirm Security Exception to add it to the list.
You should now be able to access the site without the error or further problems.
