Twitch Auto Closer is a free Chrome add-on developed by haaaa. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This program aims to automatically close duplicated tabs during raids on Twitch streams.

The main feature of Twitch Auto Closer is its ability to automatically close tabs that are duplicates of channels you are already watching. This is particularly useful during raids, as it helps to keep your browsing experience organized and clutter-free. Additionally, the add-on also has a feature that mutes the second tab of the same channel that you open, and unmutes it when you switch to a different channel.

It is important to note that the add-on mutes the Chrome tabs, not the actual video on Twitch. This means that even if you adjust the volume of the video, no sound will be heard when the tab is muted.

Twitch Auto Closer is a convenient tool for Twitch users who frequently participate in raids and want to streamline their browsing experience. It is easy to use and offers a simple solution to managing duplicated tabs during raids.
