[Mozilla Enterprise] Red-barred padlock on HTTPS sites on Firefox ESR 60

[marius.tarlo at orange.com]

Hello,

We encounter on Firefox ESR 60 the following behavior :

On some intranet sites we browse in HTTPS, Firefox displays a gray padlock barred in red near the address bar (instead of being green), telling us that there is a mixed content issue, whereas :

-       When we check the console, we don't see any HTTP request, everything is in HTTPS

-       This doesn't occur on Firefox ESR 52

-       This disappears after a while

We have set the following parameters in a .cfg file called by autoconfig.js :
lockPref("security.mixed_content.block_active_content", false);
lockPref("security.tls.version.min", 1);
lockPref("security.tls.version.max", 4);

Do you have any insight about this ?

Cordialement / Best regards,
