Manually add certificate exception

Posted

This problem is not the fault of Firefox, everything works great in vanilla Firefox (Iceweasel). My main browser is the 'Light' fork of Firefox, but the question should relevant to vanilla Firefox as well. The trouble seems to be that the project has stripped the "Add Exception" page of one of it's dependencies out of the browser.

My question is: Is there a way to add certificate exceptions to firefox without using the warning page? It would seem that being able to do so manually would be extremely advantageous for bulk setups and amnesiac machines. The only real in-browser configuration in Light is about:config and I didn't see anything obvious there, but I'm no expert. Is there a config file somewhere that houses this? Can I somehow import exceptions from Iceweasel?

This problem is affecting a page that I have to visit dozens of times a day at work and so I appreciate any help I can get. As it stands, I have to copy and paste the link and manually s/https/http/ which is quite annoying, but is still not nearly enough to make Iceweasel preferable, sadly.

If you can't inspect the certificate via "I Understand the Risks" then try this:

Open this chrome URI by pasting or typing this URI in the location/address bar to open the "Add Security Exception" window and check the certificate:

  • chrome://pippki/content/exceptionDialog.xul

In the location field type/paste the URL of the website

  • retrieve the certificate via the "Get certificate" button
  • click the "View..." button to inspect the certificate in the Certificate Viewer
