TabZero is a free Chrome extension developed by Guy that allows users to automatically close tabs that haven't been used for a specified amount of time. With this extension, users can regain valuable space for new tabs that they actually need.

Using TabZero is simple and straightforward. Users can choose the time to live (TTL) for each tab in minutes, and apply the settings. The extension then displays the remaining time for each tab before it automatically closes. If a user revisits the tab before the TTL expires, the countdown resets, giving them more time.

One of the key features of TabZero is its ability to work across multiple windows of Chrome. This means that users can effectively manage and close unused tabs from different Chrome windows, saving valuable computer memory.

By setting a specific TTL, users can ensure that tabs they haven't used for a long time will be automatically closed. For example, they can set it to 24 or 72 hours to close tabs that have been open for a few days and are no longer needed. This allows users to start each week with only the relevant tabs, ensuring a fresh start to their work.

In the latest update (version 1.0.1), TabZero has fixed the default TTL and added TTL estimation when typing, providing users with a more accurate and efficient tab management experience.

Overall, TabZero is a useful Chrome extension for those who want to optimize their tab usage and free up space for new tabs that are actually needed. It offers a simple and effective way to close unused tabs and improve computer memory usage.
