Add-on summary

Very simple add-on that displays a timer as an overlay on the Firefox browser window. Can be used to measure the time of agile meetings, e.g. on a Scrum or Kanban board. Just move it to where you want it.

The add-on adds some HTML and JavaScript to the web page you are currently viewing. So it only works when a web page is open. It will not work on an empty tab, on about:addons, or on any other tab that does not contain a web page.

Permissions:

  • activeTab: required to embed the timer into the web page
  • storage: needed to remember the last timebox used
