TST-MiddleClick is a Firefox extension designed to enhance the functionality of the TreeStyleTab (TST) add-on. This lightweight tool allows users to easily reopen closed tabs with a simple middle-click action. It is particularly useful for those who often manage multiple tabs and want to streamline their browsing experience. The extension relies on the TreeStyleTab framework to function, making it an essential companion for TST users.

The extension is subscription-based, catering specifically to users who have already integrated TreeStyleTab into their Firefox browser. It brings back a feature that was previously available through the combination of TST and TabMixPlus, now adapted for the current WebExtensions framework. TST-MiddleClick is straightforward to use and offers a seamless way to enhance tab management, making it a valuable addition for anyone looking to optimize their browsing workflow.
