Link Status Redux is a Firefox extension designed to improve link management by providing visual indicators for visited and bookmarked pages. When hovering over a link, users can see whether the link is previously visited or bookmarked, with customizable symbols and the date of the last visit. The extension allows users to configure settings such as the appearance of the indicator, including colors and positioning, as well as the format of visit dates. Users can also choose to display older visit times, enhancing their navigation experience.

In addition to the basic functionality, Link Status Redux offers advanced customization options for users familiar with coding. This includes the ability to create custom formatting for link target text using printf-style substitutions, which can display various information based on the link's status. The extension also provides a way to handle longer URLs and has limitations due to the WebExtension API, which restricts certain UI modifications. Overall, it is a valuable tool for users looking to personalize their browsing experience.
