I installed a code signing certificate in Firefox and I can't find it under Version 56.0.2 (64 bit)

more options

It's all stated above. How can I find my code signing certificate? I went on comodo's site and looked at the following page: https://support.comodo.com/index.php?/Knowledgebase/Article/View/1002/66/how-to-verify-your-code-signing-certificate-is-installed-mac (search for firefox) and I can't seem to navigate to the same place in my browser. How can I look the code signing certificates that I've installed into firefox?

The design of the Options page has changed since that article. Twice!

You can check here:

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page on the right side, type cert and Firefox should filter to the "View Certificates" button, which you can click to launch the Certificate Manager.
