@marcelloc:
So, SO and pfsense config are fine. Did you captured traffic while using firefox?
Most times, we need to close firefox and reopen to get proxy settings changes applied correctly.
To test, I rebooted the whole computer, so Firefox was restarted by design ;)
What do you mean by "capture traffic while using firefox" ?
How can I do that?
For now, on the desktops that are using firefox, I made the input manually for the WPAD file in the settings.
But I'd really like to make the auto-detect work.
Upon searching on the Google, I found out some old articles stating that Firefox does not support the DHCP way to get the WPAD file, it only supports the DNS way.
But following this article:
https://doc.pfsense.org/index.php/WPAD_Autoconfigure_for_Squid
I did add a DNS host override like so:

So it "works" but not like I wanted it to be.. that is, only setting needed on any computer is to make it auto-detect proxy settings.
I tested with IE, Safari and Chrome : all work.
Only Firefox is whimsical
