Time Tracker by Raza Jaffri

Time Tracker for Firefox puts your timer in the toolbar, so you can log work without opening another tab.

What you can do
- Start and stop the timer with one click
- Choose the project and task type, and add an optional description
- Switch between your organizations
- Keep tracking when the connection drops: entries wait in the browser and are sent when you are back online
- Recover an unfinished timer if the browser closed or the computer went to sleep

What you need
A Time Tracker account at https://timetrackersoftwarehq.com. Sign in with the same email and password you use on the web app. Two-factor sign-in is supported.

Privacy
The add-on talks only to timetrackersoftwarehq.com. It does not read the pages you visit, your tabs or your browsing history.
