TST Tab Search is a Firefox extension designed to enhance the functionality of Tree Style Tabs (TST) by introducing a powerful search box in the sidebar. Users can easily locate tabs within the current window using a variety of search options, including case sensitivity and regular expressions. The extension allows for customization of the search panel and filtered tabs, providing a tailored experience to fit individual needs. With a global search hotkey (Ctrl+Shift+F), navigating through tabs becomes swift and efficient.

The extension comes with detailed options that explain the advanced features available, ensuring users can optimize their tab management. TST Tab Search does not collect any personal data or contact external entities, ensuring user privacy. Permissions required are limited to accessing browser tabs for fetching titles and URLs, and displaying notifications for any issues encountered. This tool is ideal for users looking to streamline their browsing experience through effective tab organization.
