Sticky TabSZ

Firefox/Zen Extension to prevent tabs from multiplying like rabbits 🐰

What It Does

When you open a link matching the configured pattern, the extension will:

1. If a matching tab already exists → Close the new tab, update the existing tab with the new URL, and focus it
2. If no matching tab exists → The new tab becomes the sticky tab for that container

This prevents tab clutter when repeatedly opening links to the same type of page.
