Created attachment 104718 [details] KDE4 window with proxy settings In systemsettings → Network → Settings → Proxy → select “Use manually specified ...” you can change proxy settings only for current user. If you have more than one user you have to repeat this operation for all users. In KDE 4 selecting “manual setting” we had “Save these settings for all users” option that allow to set proxy for all users in a single operation (see attachment). Please restore this option.
