In order to set proxy in Chromium browser, one needs to go to
Settings → Under the Hood → Change Proxy Settings → Network Proxy.
It's too complicated. How do I set http_proxy in shell? I've tried
But it doesn't seem to work.
Also, if you only want to set the proxy on the Chromium browser -- not your entire network -- the command line is the only way to set the proxy just for the browser. How can one set the proxy on Chromium -- using the command line -- to solve this problem?
