Firefox doesn't work on a network with HTTPS Inspection enabled

We can use all other browsers on our network with HTTPS inspection enabled without an issue. This applies to both Windows and Mac clients.

We have our proxy's HTTPS Inspection certificate installed on all devices on the network.

Firefox is patched to the latest version.

There don't appear to be any preferences which control or enable the bypass of Firefox's SSL certificate checking.

What needs to be changed within Firefox to enable HTTPS inspection to work with it.

TIA

Firefox has its own certificate store, separate from the Mac system keychain and the Windows certificate store. You will need to insert the proxy's signing certificate into Firefox's cert8.db file.

While I could describe end user steps to import the cert manually, I suppose you need a centralized deployment solution. For that, I could only suggest a few links:
