Magic Clipper for NotebookLM

Import emails, attachments and links directly into Google NotebookLM in one click from the Thunderbird message pane. Optimized for Gemini analysis.

This release brings major robustness, security, and accessibility fixes following a thorough code audit:
- Robustness: Fixed a background PDF timer leak and a hanging PDF Promise during script injection errors.
- Security: Added message sender origin verification to prevent external injections, and fixed an invalid MIME type (.mpg).
- Accessibility (WCAG 2.1 AA): Improved text color contrast ratios in dark mode, increased attachment text sizes to 11px, added the Escape key behavior to close the notebook list, and supported prefers-reduced-motion to disable animations.
- Design: Premium polish with enhanced glassmorphism blur (14px) and active click states on all buttons.
- Metadata: Updated descriptions to accurately reflect the current feature set (emails and attachments).

Privacy Policy — Magic Clipper for NotebookLM

What this add-on does with your data
This add-on transmits data from your computer for one purpose only: importing email content that you explicitly select into your own Google NotebookLM account (notebooklm.google.com). Nothing is ever transmitted automatically or in the background — every import requires a deliberate click on an import button.

Data transmitted (only when you click an import button)

The body of the currently displayed email, converted to PDF or Markdown, including its metadata (subject, sender, recipients, date).
The attachments you have explicitly ticked for import.
The optional "research intention" note you typed.
The name you typed when creating a new notebook.

All of this is sent exclusively to Google's NotebookLM service, into your own Google account. No data ever transits through the developer's servers or any third party — there are none.

Authentication
The add-on never asks for, sees, or stores your Google password. You sign in to Google yourself, on Google's own page, in a tab opened inside Thunderbird. To authenticate its requests, the add-on reads the Google session cookies already present in Thunderbird's cookie store and periodically refreshes them with Google. Cookie values are never copied into the add-on's storage, never logged, and never sent anywhere except to Google itself.

Data stored locally
Only two preferences are kept in Thunderbird's local extension storage: the index of your active Google account and the ID of the last notebook you used. No email content, no attachments, no cookies, no tokens are persisted. The last generated PDF/Markdown is held in memory only (for the optional "Download" button) and is discarded when Thunderbird closes.

What is NOT collected
No telemetry, no analytics, no usage statistics, no crash reports, no advertising identifiers. The developer receives nothing at all. Diagnostic logging is disabled in release builds.

Your responsibility
Content you import becomes subject to Google's Privacy Policy and the NotebookLM terms, like any document you upload to NotebookLM yourself.

Source code & contact
The source code is publicly visible at github.com/mtfkarukera/mc4nblm-thunderbird. Questions: admin@magic-clipper.mtfk.fr.

This add-on is not affiliated with or endorsed by Google. NotebookLM is a trademark of Google LLC.

Beberapa pengaya meminta izin untuk melakukan fungsi tertentu (contoh: pengaya manajemen tab akan meminta izin untuk mengakses sistem tab peramban anda).

Karena Thunderbird dalam kendali Anda, pilihan untuk memberikan atau menolak permintaan ini adalah hak Anda. Menerima izin tidak secara langsung membahayakan kinerja atau keamanan peramban Anda, namun dalam beberapa kasus yang jarang terjadi, mungkin ada risiko.
