Release v6

Updated TonscanPlus to Firefox extension

The TonscanPlus project has been updated from a Google Chrome extension to a Firefox add-on. The new version includes enhanced functionality for the Open Network (TON) blockchain explorer, tonscan.org. Key features include adding custom names to TON addresses locally, filtering transactions by type, and seamless integration with tonscan.org. Current limitations are that TOP 1000 addresses are not updated in real-time and NFT Royalty addresses are manually parsed. Installation instructions have been added along with guidelines on how to contribute and support the project. Acknowledgments have also been included for key contributors to the project.
