Search with ChatGPT powered by OpenAI is a Firefox extension that integrates ChatGPT as a non-default search engine directly into the browser's URL bar. Users can easily configure the extension through the interface or by using the keyboard shortcut -L followed by 'gpt'. This allows for seamless interaction with ChatGPT, making it a handy tool for quick queries and generating responses directly from the browser.

The extension does not require any API keys, custom servers, or additional handlers, providing a straightforward user experience. Users can initiate a new thread in ChatGPT by entering commands like 'sudo make me a sammich' in the URL bar. Its source code is available for review, ensuring transparency and allowing for potential enhancements by the community.
