## Description

This extension places a tab number on each tab rendered by the (excellent) TreeStyleTab plugin.

This functionality was previously supplied by a few lines of CSS in the TST configuration, but has been broken since 4.0.1 (see: <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/325c08dc88b015416cc99c81cb335b6fbba98d83ce503b43b595f020a853b80f/https%3A//github.com/piroor/treestyletab/issues/3486" rel="nofollow">https://github.com/piroor/treestyletab/issues/3486</a> )

This extension is an implementation of the TST author's suggestion to use the TST API instead.  It has zero user-configurable options, as it hardcodes my own preferred CSS style (orange on black).
