Tab Info Exporter od OlyoshaOlyosha

A read-only Firefox extension that exports metadata of all open tabs to CSV or JSON — either to the clipboard or as a downloaded file. It never modifies, moves, or closes tabs.

Features:
- Exports all open tabs across all windows in one click.
- Output to CSV or JSON.
- Copy to clipboard or download as a file.
- 9 sort modes (by access time, open time, title, URL, or browser order).
- Selectable fields — choose exactly which columns to include.
- Runtime UI language switch between English and Russian (preference persists).
- "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.
