Untrusted Connection: without add buttom

[ahelal]

I have an error in the firefox web browser, the Untrusted connection without add button for the CA.

i have configured the UTM with Deep Inspection and add the CA to the web Browser.

but i still have this error.

does anyone know how to fix it?

This is "intended behavior" on the latest Firefox versions (> 42.0/43.0). You can override the unconditional refusal by flipping an internal variable (from v46 on this will be gone).

Open a new tab in FF, type "about:config", enter, enter.

Type "xpinstall.signatures.required", select this line and toggle from "True" to "False".

Now you can override the security warning.

IMHO this is b-s. Either I'll stay with 45.x or I'll have to change my browser.
