If you’re tired of errors, maybe skip the manual setup and use a proxy manager like FoxyProxy (works on Chrome/Firefox). It lets you switch proxies with one click and avoids most of the headaches.
For system-wide setup, Windows and Mac both have built-in options, but they’re kinda hidden. Google "how to setup a proxy on [your OS]" with your exact version—older guides might not work.
