Tab Info Exporter — Export Tabs MD, TXT, JSON, CSV автор OlyoshaOlyosha

A read-only Firefox extension that exports all open tabs to Markdown, TXT, JSON, or CSV — copy to clipboard or download as a file. It never modifies, moves, or closes tabs.

Features:
- Exports every open tab across all windows in one click.
- Four formats: Markdown, TXT, JSON, CSV. Markdown is the default.
- Live preview before you copy or download. In Markdown, links are clickable and focus the existing tab.
- Group tabs by domain, with optional tab counts per domain (TXT and Markdown).
- Copy to clipboard or download as a file.
- 9 sort modes (by title, URL, last visited, date opened, or browser order).
- 12 selectable fields — choose exactly which columns to include.
- Runtime UI language switch between English, Russian, and Spanish (preference persists).
- Settings (format, sort, fields, grouping, language) are remembered between popup opens.
- "Date opened" is tracked locally by the extension (see note below).

Privacy: everything runs locally. The extension makes no network calls and collects no data; it requests only tabs, storage, downloads, and clipboardWrite permissions.

Note on "Date opened": Firefox's tabs API exposes no real creation timestamp, so the extension records the first time it sees a tab (kept in storage.local). It does not invent a creation date.
