Build a customisable browser

Our company aims to create an ergonomic browser, which offers maximum ease of use to the users, unlike most browsers in this segment. The goal is to build a browser, based on Chromium, which allows the following inputs to be modified: cookies, UserAgent, WebGL parameters (vendor & renderer), Plugins & Fonts fingerprints, and a few others. The final product should take the mentioned settings from a .txt document and apply them onto the browser. List of all parameters which need to be modifiable in the final product: Cookies, WebGL (Vendor, Renderer, Version & DebugRenderer), UserAgent, Plugins & Fonts fingerprints, Screen resolution, Accept-Language, Timezone, WebRTC altering, Setting a Proxy, Canvas fingerprint alteringa
