Calculator автор Luka Đ.

A simple and modern calculator add-on that remembers what you were just calculating. Upon clicking its icon, you will open a pop-up that you can use to calculate without leaving your current webpage.

It also supports entry via keyboard if you don't want to click everything with your mouse. You can bring up the pop-up with the Alt+Shift+C or Shift+Alt+C keyboard shortcuts.

If you have any complaints or ideas please send an email to soommeonnee@gmail.com, leave a review or file an issue on github.
