ChatGPT Bubble Collapse 作者： Dave

ChatGPT Bubble Collapse adds small per-message controls to ChatGPT pages so you can collapse long assistant or user messages and quickly scan conversations. Buttons appear on hover (keyboard-accessible), and the extension supports per-conversation persistence so your preferred collapsed/expanded state is preserved across reloads.

Key features
- Collapse / expand individual message bubbles
- Context-menu actions: "Collapse all" and "Expand all"
- Configurable number of visible lines when collapsed
- Per-conversation or per-bubble persistence (configurable)
- Keyboard-accessible controls (Tab + Enter/Space)
- Works with ChatGPT at chat.openai.com and chatgpt.com
- Privacy-first: no message content is uploaded or transmitted

Permissions used
- storage — save user settings and collapse states locally
- tabs — verify and target active ChatGPT tab for context-menu actions
- menus — add "Collapse all" / "Expand all" context menu items
- Host permissions: access pages under https://chat.openai.com/* and https://chatgpt.com/*

Notes for users
- For development/testing, install as a temporary add-on via about:debugging. A signed XPI is required for regular installs on release Firefox builds (submit to AMO for signing).
- The extension operates entirely locally and does not send message content to any server.

Support
Open an issue or PR in the repository with steps to reproduce if anything breaks after ChatGPT UI changes.
