Nofollow Link Check Firefox

Nofollow Link Check

Highlights nofollow, dofollow, UGC, sponsored, and JavaScript links with color-coded borders for easy SEO insights.

Features & Capabilities

Highlight Links Plugin is a browser extension designed to help users easily identify different types of links on web pages. By using a color-coding system, the plugin makes it simple to spot the nature of each link, providing greater insight into web page content.

The plugin applies a color-coding system to distinguish between various types of links:

  • Dofollow links: These links are standard links that allow search engines to follow and index them. They are outlined in green.
  • Nofollow links: These links instruct search engines not to follow or index them. They are outlined in red.
  • UGC links: Links marked with the ugc attribute, typically used for user-generated content, are outlined in blue.
  • Sponsored links: Links marked with the sponsored attribute are associated with paid content and are outlined in orange.
  • Neutral links: These links have attributes like noopener or noreferrer, indicating they don’t pass referrer information. They are outlined in light gray.
  • Javascript links: Links that begin with javascript: or have an empty href attribute are outlined in gray.
Links that are not recognized or colored by the plugin:
  • Links without an href attribute or with javascript: URLs may be missed in certain scenarios.
  • Links that do not include rel attributes are considered neutral and may not receive a specific color.
  • The plugin does not highlight links that are dynamically generated by JavaScript after the page load unless manually triggered.
The plugin is a valuable tool for web developers, SEO professionals, and anyone interested in better understanding the types of links on a webpage. It is designed to provide a clear and efficient way to identify the relationships between pages, making browsing and analysis more transparent.

Is Nofollow Link Check 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.

Nofollow Link Check 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.

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.
