Thunderbird Installation
Choose your preferred installation method.
Download and run the installer for your platform. If Thunderbird is not installed, the installer can download and install the official Mozilla Thunderbird build. It will then configure Thunderbird to install the TabMail add-on for all users and set up the required native full-text search helper.
For users who already have Thunderbird installed or prefer manual control over the installation process.
Step 1: Install the Add-on (XPI)
Download the Thunderbird add-on and install it manually into your existing Thunderbird installation.
tabmail-latest.xpi- Download the XPI file above
- Open Thunderbird
- Go to Tools → Add-ons and Themes (or press Ctrl/Cmd + Shift + A)
- Click the gear icon ⚙️ and select "Install Add-on From File..."
- Select the downloaded XPI file
Step 2: Install the Full-Text Search Helper (Required)
Hybrid search needs a small native helper that builds your search index on your device. It runs entirely on your machine — nothing is uploaded. No admin/sudo required; it installs to your user folder.
curl -fsSL https://raw.githubusercontent.com/TabMail/tabmail-native-fts/main/scripts/install.sh | bash
Prefer to inspect it first? Read install.sh on GitHub → It downloads our notarized helper binary and registers it with Thunderbird — nothing else.
- Open Terminal
- Run the command above (no sudo needed)
- That's it — no need to restart Thunderbird
irm https://raw.githubusercontent.com/TabMail/tabmail-native-fts/main/scripts/install.ps1 | iex
Prefer to inspect it first? Read install.ps1 on GitHub → It downloads our helper binary and registers it with Thunderbird — nothing else.
- Open PowerShell (no admin needed)
- Run the command above
- That's it — no need to restart Thunderbird
The Full-Text Search Helper is a small native program that builds a private search index of your mail on your device, powering TabMail's hybrid keyword + semantic search. It runs entirely on your machine — nothing is uploaded. No admin required, it installs to your user folder, and you don't need to restart Thunderbird.
Signed & notarized. Installs to your user folder (no admin), and there's no need to restart Thunderbird — TabMail detects the helper automatically.
Manual install (or Linux)
Prefer a script, or running Linux (no one-click installer)? Run the one-liner for your platform instead.
