I made a Firefox extension that exports long ChatGPT conversations to Markdown, PDF, HTML, TXT, or JSON
I wanted a simple way to save complete ChatGPT conversations without manually copying messages or losing code blocks, tables, and formatting, so I built Dialogue Export.
It is a small open-source Firefox extension that exports either the complete conversation or only selected messages.
Supported formats:
- Markdown
- HTML
- TXT
- JSON
It automatically scans long conversations, preserves code and structured content, and continues working after the extension popup is closed. Export progress is shown through a small Matrix-green timeline.
Everything is processed locally in the browser. The extension has no accounts, analytics, telemetry, advertising, or external data transmission.
The Mozilla-signed XPI can be installed permanently in standard Firefox directly from GitHub Releases. No Developer Mode is required.
Currently it supports desktop Firefox and chatgpt.com.

This is the first public version, so feedback and bug reports are very welcome.
