Not sure if this is already reported, But I don't have the settings button.
JS Console reports:
Uncaught TypeError: Cannot read property 'textContent' of undefined hvstat.user.js:239
Never used HV Stat before. Just installed it, shows up in the Extensions but I don't know how to open it.
From the JavaScript console I get the following:
onupgradeneeded hvstat.user.js:3069
Uncaught TypeError: Cannot read property 'textContent' of undefined hvstat.user.js:239
