AdLighter's Chrome add-on, Adlighter, serves the purpose of preventing accidental clicks on ads by enhancing them visually. The latest versionincludes the removal of eBay due to required improvements and CSS fixes for Coupang. The developer's motivation behind the extension was to offer users a way to avoid unintended ad clicks while still being able to view ad content.

Adlighter functions by overlaying red boxes and a blue background on sponsored search results and ads across various supported websites such as Amazon, Reddit, Google, Pinterest, and Coupang. Users can easily identify sponsored content through these visual cues, enhancing their browsing experience and reducing the risk of inadvertent ad interactions.
