OneTab is a Firefox extension designed to help users manage their browser tabs efficiently. With a simple click on the OneTab icon, all open tabs are converted into a list, reducing memory usage and CPU load. This feature is particularly useful for users who often find themselves overwhelmed by multiple tabs, allowing them to restore tabs individually or all at once whenever needed. Additionally, OneTab offers privacy assurance, ensuring that tab information is not shared unless the user opts to share it as a web page.

Beyond just tab management, OneTab enhances browser performance by potentially speeding up the computer and facilitating quicker resume from sleep mode. It provides various options for organizing tabs, including the ability to exclude websites, remove duplicates, and export or import tab lists. OneTab's functionality makes it a valuable tool for anyone looking to optimize their browsing experience.
