Ionic Serve Breaks Other Web Apps

When I am serving my app using Ionic serve, i notice that alot of other apps are broken for example facebook has this weird error that stops me from posting anything. same for Github, medium actually fails to even load with some error on page. Has anyone else experienced this?

Are you using a CORS extension by chance? I’ve experienced the same on Google Chrome when the CORS plugin is enabled.

Spot on using the Chrome cors plugin. DO you know exactly why the problem occurs if so I can aim to write a fix or somthing because ionic without facebook is a bit not so cool lol
