Theme Tool - By Mr.Bear 作者： Mr.Bear

Theme Manager lets you quickly change between your installed Firefox themes directly from the toolbar. It also includes built-in dynamic light and dark themes that can be applied instantly without installing anything extra. All actions run locally in your browser, and no data is collected.

Use it to:
• Switch installed themes with one click
• Apply temporary dynamic light or dark themes
• Keep the popup open while switching themes
• Manage themes without opening about:addons

This extension is lightweight, privacy-friendly, and designed for desktop Firefox.
