Browser cannot use system proxy settings

Is there any reason for an app to *not* use the system proxy settings? If not, this isn't a bug in the browser, it's a bug in network-manager. Expecting the developer of every Internet-using app to know and care about proxies, and test that they work, is not a credible approach.

Agree with mpt, we should be consider the system-wide proxy settings in network-manager instead of standalone proxy feature for each application.But for now, still can't find a way to configure the proxy in settings.

That System Settings currently has no UI for proxy settings is a separate problem from Network Manager not making it transparent when you set it with gsettings.

Added a task for ubuntu-system-settings since there would need to be a panel implemented to change this on the phone.

FWIW, seems like the browser works if /etc/environment is modified, which is something that implementing a panel in system-settings might fix if it works similarly to the GNOME proxy settings (setting gsettings keys and PROXY environment variables in /etc/environment).

Adding to #4, the entire system needs to be restarted for changes to take effect.

Given the number of folks this affects priority should be higher?

I would recommend not to have system-wide proxy settings, but proxy setting for every connection. Since there could be different proxy servers in different locations. Each WiFi AP should have his own proxy settings saved. This also implies gui setup for proxy.

Problem still exists in the UBPorts image.
