A dot marks a day the store showed a different number. Between them the line carries the last one forward: we read every listing up to 2 times a day and record a point only when something moves. History beyond ninety days is in the app.

What it can reach

  • Run its own code on the pages it can access scripting
  • Act on the current tab, but only after you click it activeTab
Show the remaining 3
  • Keep running while the browser is open background
  • Add items to the right-click menu contextMenus
  • React to what a page contains without reading it declarativeContent
