It's a must-have add-on if you care about your privacy. Intuitive, easy to use and absolutely customizable. I love it! A WARNING FOR MACOS USERS: Keyboard shortcuts ⌘⇧[3 to 5] are already taken by the OS (macOS screenshot shortcuts). But if you switch them in Add-ons Manager > click the gear > Manage Extension Shortcuts to ⌥⌘[number] it works just fine.
