Build me an Android browser app like a more customizable Firefox based browser.

I want it to let people browse normally with tabs, incognito mode, reader mode, desktop mode, popup protection, and data saver, but also have built in extension support so users can install Firefox add ons from the store or from an XPI file. It should include a media capture feature that detects downloadable video, audio, and subtitles on pages, including common stream types like HLS and DASH, plus a download manager with pause and resume, speed control, scheduling, and custom download locations.

Make the UI feel modern and polished with Material 3 and lots of theme choices, light and dark modes, and customization options. Add privacy features like tracking protection, secure DNS, fingerprinting protection, app lock, clear data on exit, and no telemetry or backend. If needed, look up the current docs online for GeckoView and Android implementation details.
