ChatGPT in Sidebar is a Firefox extension that allows users to access the ChatGPT web application directly from the browser's sidebar. This tool enhances productivity by providing quick access to ChatGPT's capabilities without navigating away from the current webpage. The extension includes a toggle button and a keyboard shortcut (Alt+Shift+C) for easy access, which can be customized in the options menu. Users who prefer a more visual approach can utilize the toolbar button to open and close the sidebar.

To optimize the user experience, the extension provides guidance on unlocking the sidebar width in Firefox, as it is locked by default. Although the extension enhances functionality, it operates independently of ChatGPT and OpenAI, serving primarily as a personal project for individual use. Overall, this add-on offers a convenient way to utilize ChatGPT while browsing, making it a valuable tool for users looking to streamline their workflow.
