If your browser can install Chrome extensions, you'll need to head over to this link to get the official ChatGPT Search extension. It's the same link that OpenAI offers on its website, at this link.

OpenAI's new "ChatGPT search" Chrome extension feels like nothing more than a typical search hijacker, changing Chrome's settings so your address bar searches go through ChatGPT Search instead.

On Firefox, the process of making ChatGPT your search engine is quite different from Chrome and Microsoft Edge. Open Firefox on your computer, type about:config in the address bar, and press Enter.
