All seems working fine without any issues here.
I thought that it needed a Greasemonkey to run the script.
after unzip the size of the folder or file is around 34kb it's pretty light and only contains 2 .js files, HTML, icons, license, ,JSON and READme it seems you forgot to edit Readme it contains other forum sites and the .js contains bitcoindata.science APIs.
Anyway, the only thing that I want to suggest is I think adding a script or code for the balance or transaction ID like a popup box where you can paste TXID or address, or a typing box below these two buttons?
