Features & Capabilities

SiteDelta Highlight is a powerful Chrome extension that helps you easily identify changes made to any website since your last visit. By adding a simple Delta icon to your browser toolbar, it allows you to highlight all altered text content on the current page with a single click.

Advanced configuration options enable automatic highlighting of changes on known pages every time you visit, as well as periodic checks for updates. For change notifications without opening pages, you can use the complementary SiteDelta Watch extension. SiteDelta Highlight is an essential tool for users who want to stay up-to-date with content changes effortlessly.

Is SiteDelta Highlight 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.

SiteDelta Highlight does not require any sensitive permissions.

Risk impact analysis details

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.

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