issues with proxy firefox 106.0

more options

I am trying to setup proxy server for Firefox 106.0 on my Windows 11 Laptop. I have Windows 11 setup to provide system proxy settings to a local intranet squid proxy server at port 3128 with a configuration file. With this setup both google chrome and Microsoft Edge find the proxy and correctly utilize it. when I use Firefox and watch the squid logs the proxy is bypassed when settings are set for "use system proxy settings, no proxy, automatic proxy configuration url" If i set to manual proxy configuration it works.

You will have to contact the proxy server your using to configure the settings.

Were the other settings working in Firefox 105 and earlier? (If you used the same configuration with Firefox before this week's update.)

Yes. earlier versions worked as expected. Under Windows 11 there is a system wide proxy setting that steers the system connection. When I point this to my squid proxy server it works as expected when I browse with chrome and edge, and previous versions of firefox. With Firefox 106 it just does not work and I have to manually input the proxy site settings.
