Email Extractor for Firefox

Pull the email addresses from the page you are viewing, select the ones you want, and copy or export them as TXT or CSV. It runs entirely in your browser.

Status: submitted to Mozilla Add-ons and in review. Mozilla signs every listed add-on before installation, so there is no install link yet. Until it is approved, use the web Email Extractor with pasted text or a file, or the Chrome extension.
How it works

Three steps

  1. Open a web page and click the add-on (or press Ctrl+Alt+E).
  2. Press Extract. Addresses from visible text and mailto links are listed once each.
  3. Copy, download TXT/CSV, or copy and open them in the ValidReach Email Extractor.
Permissions

What it asks for and why

  • activeTab — Lets the add-on read the tab you are on only after you click its button or press Ctrl+Alt+E.
  • scripting — Runs the small reader that collects the page’s visible text and mailto links.
  • storage — Holds the selected addresses in temporary session memory for up to 5 minutes.
  • clipboardWrite — Lets “Open in ValidReach” copy your selection before opening the Email Extractor.

It requests no access to all websites, history or cookies. See the browser extension privacy notice.

Limits

What it does not do

  • Reads the top frame of the current tab only; iframes and closed shadow DOM are not read.
  • Hidden elements, scripts and form fields (inputs, text areas, editable regions) are ignored.
  • Up to 2,000,000 characters and 10,000 unique addresses per run; larger pages give a partial result and say so.
  • Browser pages (about:) and addons.mozilla.org cannot be read.
  • It finds addresses; it does not verify that they work.
