Features & Capabilities

MOC Source overlays live LEGO Pick a Brick (PAB) and Bricks and Pieces (BAP) prices directly onto BrickLink.com — on wanted lists, store carts, store listings, and catalog pages — so you can see at a glance whether a part is cheaper from LEGO direct or from the BrickLink store you're browsing.

Click the toolbar icon to open the built-in list manager: import your BrickLink wanted lists and store carts, track Want/Have quantities, and compare LEGO-direct pricing part by part. The Projects workspace lets you split a wanted-list pool across multiple LEGO Pick-A-Brick carts and BrickLink store carts, auto-allocating each part to its cheapest source and tracking savings including shipping.

Price badges work on BrickLink's public pages with no account needed. Importing your own wanted lists/carts requires a free BrickLink.com account (data stays local to your browser). LEGO cart transfer requires a LEGO.com login.

Free and open source (AGPL-3.0). Built by an AFOL, for AFOLs — not affiliated with the LEGO Group or BrickLink.

Is MOC Source 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.

MOC Source 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.

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