HaveAccording to your tutorial , your shadowsocks client ( ss-local ) exposes a SOCKS-5 proxy , and you tried this onecan use that SOCKS-5 proxy for all your connections in Firefox ?, but as it shows in your screenshot , you are using the HTTP proxy section of your Firefox , just fill out the SOCKS5 section and remove HTTP proxy section on your Firefox proxy settings and it should work just fine , but if you you need to use the HTTP proxy on port 1080 , you can use the Qt5 version the Qt5 version is working very well for me and you have greater control over your proxy settings .

it has a nice GUI and it opens a http/s proxy on port 1080 that can be used as you global proxy or Firefox proxy .

Have you tried this one ? the Qt5 version is working very well for me .
