My mobile internet suddenly has stopped working. Chrome complains Error 130 (net::ERR_PROXY_CONNECTION_FAILED). Google app store and other apps those load content from servers now work only when I connect through wifi.
I set in firefox about:config network.proxy.type from default value 5 (use system settings) to 0 (no proxy) and firefox has started working.
Proxy Settings app shows empty fields.
As I don't use any proxy I would like to see that system wide proxy setup which broke my mobile inet
