Features & Capabilities

When comparing several products, there's no built-in way to see which shops stock all of them. Multi-Product Comparator lets you add products to a compare list and highlights shops that carry every added item — directly on the offer list.

How it works:

Visit a product page on a supported site
Click "Add to Compare" (floating panel, bottom-right)
Open another product page — shops carrying all your added products are highlighted in green
Manage the list on the page or via the toolbar popup

Supported sites: • idealo — idealo.de, idealo.at, idealo.fr, idealo.es, idealo.it, idealo.co.uk • Geizhals — geizhals.de, geizhals.at, geizhals.eu, skinflint.co.uk, cenowarka.pl • billiger.de • guenstiger.de

Each site keeps its own separate compare list. UI is localized (German, English, French, Spanish, Italian, Polish). Your list lives in session storage only — it clears when you close the browser. No accounts, no tracking, no data collection.

Is Multi-Product Comparator Safe?

Risk impact

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.

Multi-Product Comparator requires a few sensitive permissions. Exercise caution before installing.

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.

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