How can I change the proxy settings for Google Chrome?

"Google's help docs show how to do this:

Click the wrench menu tools menu.

Select Options.
Click the Under the Hood tab.
In the 'Network' section, click the Change proxy settings button. This will open the 'Internet Properties' dialog box in Windows where you can adjust your network settings. See here for more details."

"When running Google Chrome under a supported desktop environment, the
system proxy settings will be used. However, either your system is not
supported or there was a problem launching your system configuration.

But you can still configure via the command line. Please see man
google-chrome for more information on flags and environment variables.

Running the latest Chrome on Xubuntu & it's possible to start it with Terminal, so that it will use a localhost proxy called Privoxy:

google-chrome --proxy-server=""https=127.0.0.1:8118;http=127.0.01:8118""

However, this doesn't stick and it isn't simple to edit the menus to use it. I'm looking for a way to insert the proxy information in .config/google-chrome but so far it's just wishful thinking."

The Proxy SwitchOmega extension does what Proxy SwitchySharp is supposed to do except it actually installs as of Chrome 56 (because this is not NPAPI type).
