does not recognize 'no proxy for' setting (in Firefox) properly

[tmeidinger]

Browser: Firefox 120.0.1
OS: macOS 14.2

If e.g. 192.168.0.0/24 is set in the Firefox 'no proxy for' setting. FoxyProxy 8.2 is not proxying for 192.168.*.*.

Do you mean "No proxy for" in Settings -> Network Settings -> Connection Settings?

That setting is only applicable when setting a Remote PAC.

Try setting it in Global Exclude.

The network on the LAN is 192.168.0.0/24 and version 8.2 doesn't proxy 192.168.178.* any more. Regex rule is ^https?://192.168.178(.\d+) (not working) but e.g. ^https?://10.0.0(.\d+) is working. Even if I am selecting the proxy manually (for all traffic) it's showing in the log 192.168.178.1 is not sent to the proxy.

I downgraded to version 7.5.1 and everything is fine again.

192.168.0.0/16 is set as global exclude in FoxyProxy in Firefox since it is local network.

Do you want to go to 192.168.0.0/16 via a proxy?

[tmeidinger]

192.168.0.0/24 is the local network. I want to go to 192.168.178.0/24 via a proxy.

There is no such thing as a Class B network.

It seems to me as if this is a different issue. Localhost 127.0.0.1/8 is a different issue from 192.168.0.0/24 not being 192.168.0.0/16.

[erosman]

FoxyProxy 8 is hardcoded to bypass proxy for localhost and local networks.
192.168.0.0/16 is often used for Wi-Fi modem/router and they shouldn't really be proxied.

The issue of local network proxy bypass is discussed in #50.

[tmeidinger]

The internet is classless. If I'd like to route 192.168.0.0/30 (on the internal network) that's ok with every RFC I know. The same goes for proxying. There is absolutely no reason to exclude rfc6761 (former rfc1918) IP space.

I am discussing the issue with the founder of FoxyProxy and some or all of localhost checks will be removed in v8.4

[erosman]

It is done in v8.4
We are uploading v8.4 to AMO.
FoxyProxy Basic (same code) will be available shortly but FoxyProxy (standard) will take time due to the AMO review process.
