Display Anchors is a Firefox extension designed for web developers to easily visualize and navigate through invisible anchors on a webpage. This subscription-based tool simplifies the process of linking to specific sections by marking all anchors, allowing users to see where each anchor is located without disrupting the existing page layout. The extension ensures that markers do not cause any layout shifts or repaint issues, maintaining a smooth browsing experience.

Key features include hover highlights for both the markers and the anchored content, providing intuitive visual cues for users. Additionally, the extension offers a convenient toolbar button to remove all markers and a customizable label option for displayed anchors. The ability to toggle anchors using a keyboard shortcut (Alt + Shift + A) further enhances usability, making Display Anchors a valuable asset for efficient web development.
