## Description

Auto Tab Groups is a versatile Chrome extension that automatically organizes your browser tabs by domain or subdomain to enhance your browsing efficiency. Compatible with both Chrome and Firefox through a single codebase, it offers powerful features such as customizable grouping rules, minimum tab thresholds for group creation, and smart domain display that cleans up URL appearances.

Whether you want automated or finely tuned tab organization, Auto Tab Groups streamlines your workflow by decluttering your browser.
