Text Format Toolkit от Walter

Text Format Toolkit is a lightweight Firefox extension that provides multiple text formatting and cleanup tools directly inside a simple popup interface.

Users can paste or type content and quickly perform common text operations such as uppercase conversion, lowercase conversion, whitespace normalization, word counting, and line reordering.

All processing is performed locally inside the browser using client-side JavaScript without external communication or remote processing.

The extension is designed for quick productivity tasks, lightweight formatting workflows, and educational text manipulation.
