    I'm looking for a skilled developer to create a Firefox extension (add-on) that will use both simple scraping and Chat GPT API in order to send customized prompts (based on the scraped elements) and receive responses. The workflow will be very simple: 1. The user will come to a website and start the extension, which will extract 5 different text elements (these will be pre-selected). 2. After that, the extension will automatically modify the prompt (input the extracted data to the template prompt) and then send it to Chat GPT API. 3. It will display the response from Chat GPT API.
