Auto Tab Timer – Tab Coun

Auto Tab Timer is a browser extension and tab countdown timer that lets you automatically close any tab after a set amount of time.
Use it to set timers for tabs so they close automatically, helping prevent tabs from staying open too long. It is ideal for videos, background tabs, and overnight browsing.

Works on Chromium-based browsers.
