Basic Squid Installation/Configuration Support Request

[baqwas]

Hello!

I have Squid up and running with the initial defaults. Unfortunately, Firefox (under Ubuntu 25.10) cannot use the service if it is directed to do so by Squid's <OPNsense server IP address>:3128.

Pardon me, but uploading screenshots is easier for me than typing in the all the configuration settings (mostly default). Please let me know if you see something obvious that I have set incorrectly (or need to specify explicitly). I have a feeling that Squid gets the packets but doesn't send them anywhere. Any advice would be appreciated. Thanks.

Regards.
