Bitcoin blocks tracker

This extension was created to easily and conveniently track the emergence of new blocks in the Bitcoin network. After the new block is mined, the extension notifies the user with a sound signal. The extension also allows you to quickly monitor current commissions on the network and set notifications to a specific fee level. Obtaining blocks and fees data is done using mempool.space GitHub: https://github.com/IvanSavoskin/bitcoin-blocks-tracker-extension
