Open source Firefox extension to quickly interact with an LLM on current webpage (github.com)

Noice — an open-source, “bring your own key” Firefox extension — provides instant access to LLM assistants (OpenAI, Anthropic, Google Gemini) from any webpage via a keyboard shortcut (default Ctrl+J). It opens an overlay where you can include the current page’s content in prompts using @page, get streaming responses rendered with full Markdown (code blocks, lists), and keep conversation history for the session (cleared when the popup closes). Models are selectable per provider, and interaction uses familiar keys (Enter to send, Shift+Enter for newline, Escape to close). The extension is MIT-licensed. Installation is done by loading it as a temporary add-on (about:debugging → Load Temporary Add-on) and configuring provider and API key in about:addons → Noice preferences; API key endpoints: platform.openai.com/api-keys, console.anthropic.com/settings/keys, and aistudio.google.com/app/apikey. You can change the shortcut via about:addons → Manage Extension Shortcuts. Significance: Noice gives researchers, developers, and knowledge workers a low-friction, privacy-friendly way to query LLMs with live page context and streaming feedback, enabling fast summarization, code extraction, and in-situ assistance while keeping API keys under user control.
