Features & Capabilities

Check iframe is a Firefox extension that helps you identify iframe and frame usage on any web page. It indicates the presence and type of tags by color-coding the icon (gray for unchecked, green for no tags, orange for tags detected, purple for a source match). The extension can also scroll to the relevant elements and highlight them with a red border for quick inspection.

It includes an optional redirection feature to automatically navigate to the first iframe source on configured sites. Setup and usage are documented with links to the official docs and the GitHub repository for easy configuration and customization.

Is Check iframe 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.

Check iframe requires some sensitive permissions that could impact your browser and data security. 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.

Check iframe is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
