Features & Capabilities

Is that €79 jacket really worth it? True Cost shows you: it's 5 hours and 16 minutes of your work.

True Cost is a simple browser extension that converts product prices on any website into work-time equivalents, based on your net hourly wage.

HOW IT WORKS

Set your hourly wage in the settings popup
Browse any online shop — Amazon, Zalando, eBay, Otto, or any site with prices
Prices are automatically converted into work-time (e.g. "3h 12m" instead of "€79,99")

The converted text appears in the exact same font, size, and color as the original price — it blends in perfectly and looks completely native.

FEATURES • Perfect style matching — replaced prices look identical to originals • Flexible display — choose what shows by default vs. on hover • Multi-price support — converts ALL prices on a page • Works everywhere — Amazon, Zalando, eBay, Otto, and any other shop • SPA compatible — works on dynamic single-page apps • Supports €, $, £ currencies • Handles European (1.299,00) and US (1,299.00) number formats

PRIVACY True Cost is 100% local. It collects zero data, makes zero network requests, and uses zero analytics. Your wage and settings stay on your device. The source code is fully open for inspection.

PERMISSIONS EXPLAINED • Storage: to save your wage and preferences locally • Host permissions: to detect prices on the page you're viewing

Is True Cost 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.

True Cost requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

True Cost is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
