Features & Capabilities

Difframe overlays a reference website or Figma prototype on top of the page you're building — as a live iframe, not a screenshot — for pixel-perfect comparison.

Because the overlay is a real page, it always reflects the latest version of your reference and scrolls like the real thing.

Features:

Difference blend mode: matching areas turn black, so misalignments stand out instantly
Scroll sync between your page and the overlay
Explicit input-target switching: send clicks and scrolls to the page or the overlay
Presets saved per page or per host: URL, opacity, scale, size, position, blend mode
Tab scope: override the preset in a single tab, e.g. to compare desktop and mobile side by side
Image mode as a fallback for sites that refuse to be embedded (paste or drop an image)
Paste a Figma share link as is — it is converted to the embed URL automatically

Difframe collects no data. To display the reference page in an iframe, it removes frame-blocking headers (X-Frame-Options / CSP) only in tabs where the overlay is enabled, via per-tab session rules that are deleted when the tab closes. Other tabs and normal browsing are unaffected.

Is Difframe 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.

Difframe 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.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

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.

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