An error I recently received while updating Firefox 3.6.x. After the update I was not able to connect to any of my https ssl sites. After some “googleling”, I found a solution that consists of fragments I found on different sites.

Basically I needed to delete the file cert8.db which can be found in you’re profile directory. If you don’t know where to find you’re profile directory, execute the “Tools: Error Console” from within Firefox.

Paste the following command as one line and hit the button “Evaluate”:

Components.classes["@mozilla.org/file/directory_service;1"].getService( Components.interfaces.nsIProperties).get("ProfD", Components.interfaces.nsIFile).path

It will show you where to find your profile directory.

Cheers,

Ray.
