Thunderbird Second Brain 0.2.0

The add-on becomes Thunderbird Second Brain: the thread summarizer is now
one of three tabs, next to saving mail into an Obsidian vault. Repository
renamed from tb-thread-summarizer to thunderbird-secondbrain (the add-on id
is unchanged, so existing installs update in place).

Added

• Salva tab: saves the displayed message into the vault through the
  Obsidian Local REST API — a verbatim Markdown note with a fully quoted
  frontmatter (Message-ID, thread key, sender, recipients, date, subject,
  client, matter, attachments, .eml path, SHA-256, account, PEC flag), the
  real attachments as files, and the original .eml (always for PEC accounts,
  on request otherwise) with its SHA-256 fingerprint. A line is appended to the
  «Cronologia» section of the matter (or of the client card), and the message
  gets a vault tag in Thunderbird (created if missing).
• Client suggestion from the sender: exact address, then domain/subdomain,
  read from the client cards in the vault (domini, email frontmatter).
• Destinations: client (with optional matter), personal correspondence, vault
  inbox. Idempotent: a message already in the vault is detected by Message-ID.
• Inline parts referenced from the body (signature logos, embedded images:
  contentId or Content-Disposition: inline) are not saved as attachments;
  the popup reports how many were skipped.
• Promessa tab: creates a «Promessa» note (with prossima_scadenza and
  calendario, so the calendar projector picks it up) or registers a deadline
  on the matter (prossima_scadenza updated only when the new date is
  earlier, plus a line under «⏰ Scadenze»).
• Options: Obsidian URL and API key with a connection test, vault folders,
  Thunderbird tag name, per-account PEC flag.
• Pure, dependency-injected modules with unit tests: vault-client,
  frontmatter, anagrafica, nota-corrispondenza, salva, promesse.

Changed

• Popup title «Second Brain»; the summary starts when its tab is opened (the
  last used tab is remembered). Summary code and protocol are unchanged.
• Default model preference: granite4, gemma3, llama3, qwen2.5 (qwen3 avoided).
• Permissions: messagesUpdate, messagesTags, accountsRead added; host
  permissions for localhost:27123 / 127.0.0.1:27123 (Obsidian) added.

Install: download the .xpi below, then in Thunderbird → Add-ons → ⚙ → Install Add-on From File…. Existing 0.1.x installs update automatically.

v0.1.3 — automatic updates

Automatic updates are here. From this version on, Thunderbird checks this
repository for new releases and updates the add-on on its own — no more manual
reinstalls. (Thunderbird does not require add-on signing, so this works without
any signing step.)

One last manual step

This is the version that introduces the auto-update mechanism, so it has to
be installed by hand once:

1. Download tb-thread-summarizer-0.1.3.xpi below.
2. Thunderbird → Add-ons Manager → gear → Install Add-on From File….

From 0.1.4 onward, updates install automatically.

CHANGELOG.

v0.1.2 — correct message-count plural

Small fix: the panel now shows "1 messaggio" (correct Italian singular) instead of "1 messaggi", in both the generation line and the summary meta line.

Install: download tb-thread-summarizer-0.1.2.xpi below → Thunderbird → Add-ons Manager → gear → Install Add-on From File.

v0.1.1 — clearer errors + persistent OLLAMA_ORIGINS

Maintenance release.

• Clearer error when Ollama can't be reached. The panel now explains both
  possible causes — Ollama not started, or started without extension permission
  — and shows the OLLAMA_ORIGINS command inline. (A CORS rejection reaches the
  browser as a plain network error, so the two cases can't be told apart at
  runtime; the message now covers both.)
• Persist OLLAMA_ORIGINS across reboots. New
  scripts/persist-ollama-origins-macos.sh installs a per-user LaunchAgent so
  you don't have to re-run launchctl setenv after every restart.

Install

Download tb-thread-summarizer-0.1.1.xpi below → Thunderbird → Add-ons
Manager → gear → Install Add-on From File….

CHANGELOG.

v0.1.0 — first release

First public release of Thread Summarizer for Thunderbird.

Adds a Riassumi thread button to the message header that summarizes the
current email thread with a local Ollama model — TL;DR, key points,
actions & deadlines, and who is waiting for a reply. Nothing leaves your
machine.

Install

1. Download tb-thread-summarizer-0.1.0.xpi from the Assets below.
2. Thunderbird → Add-ons Manager → gear icon → Install Add-on From
   File… → pick the .xpi.

Requires Thunderbird ≥ 128 and Ollama running locally
(e.g. ollama pull gemma3). One-time setup so Ollama accepts the extension:

launchctl setenv OLLAMA_ORIGINS "moz-extension://*"   # macOS, then restart Ollama
