A:Answer Hi there! Thank you for reaching out with your question.
The Pioneer 50" Class LED 4K UHD Smart Roku TV (Model PN50‑R851‑26U) does not include a built‑in web browser. Roku TVs are designed primarily for streaming apps, but you can still browse the internet by screen‑mirroring from a phone, tablet, or computer.
If you need help setting that up, we’re happy to assist! Have a great day. Vennila | Pioneer Products
