Features & Capabilities

Cennik tracks product prices and shows the honest history — so you know whether a “sale” is real.

Wildberries & Ozon — one-click «Track price» button right on the product page
Any store — schema.org, microdata, meta tags, SPA state; an eyedropper for tricky sites
Price history — charts, min/max/average, target price with progress bar
Alerts — browser notifications + optional Telegram via your own bot token
Privacy first — no accounts, no cloud, no analytics; everything is stored locally, JSON export included

Some SPA stores are checked by briefly opening a background tab — that's how Cennik reads prices that anti-bot protection hides from plain requests.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Cennik - Price Tracker is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
