Is there any plugin or setting for firefox that can simplify the invalid SSL certificate process to a single click, or even not put up any errors and just display a warning indicator?

Working on a dev network using self-signed cerificates for initial design means contantly having to go through the 5 step process to grant an exemption for a site, which is a real pain when swapping things around.


You can use this addon to change the certificate acceptance behavior in Firefox:

    That add-on was disabled on the Mozilla site... I guess they considered it too great a security risk. – ZeroBugBounce Aug 24 '11 at 16:22

Talk to your sysadmin. They can setup a CA on your domain (assuming a Windows network here). Have the dev servers use certs from that internal CA, which will be trusted by all machines on the domain.

    +1 for CA. You can accomplish a CA certificate setup with openssl. If that is too daunting you could also use a GUI like TinyCA. – Alex Sep 25 '09 at 3:10

One thing you might want to consider doing is to simply self sign a wildcard certificate for use on your development network. Then install that wildcard cert on all the systems. Once you accept the certificate once it should be good everywhere.

  • This would work, but setting up a CA and trusting the CA to sign certificates for individual hosts is a better solution. – Alex Sep 25 '09 at 3:04
  • @Alex, I agree, but if it is for testing/dev and the network is only going to be around for a short time, then it might not be worth the effort. – Zoredache Sep 25 '09 at 3:51
