Price Tracker από exzzy

Price Tracker watches product prices in the background and sends you a
Firefox notification the moment a price changes.

Features:
• One-click tracking — open the popup on any product page, the price is
detected automatically, click "Track price"
• Works on Amazon, WooCommerce stores, and any site using standard
product markup (JSON-LD, Open Graph, Schema.org microdata)
• Manual element picker for sites the auto-detector doesn't cover
• Configurable check interval (default: every 60 minutes)
• Per-item price history
• Badge counter for unread price changes

Opening Price Tracker:
• Desktop — click the Price Tracker icon in the toolbar.
• Firefox for Android — Android has no add-on toolbar buttons, so open it
from the menu. While you're on a web page (not the Firefox home screen),
tap the ⋮ menu → Extensions → Price Tracker. The popup opens with the
detected price and your tracked list; the expand icon in its top-right
corner opens the full tracked-items page.
