Maybe it's because I have all the privacy features on Firefox enabled but I tried turning cookies on for this extension to track my time on the clock but it didn't work. Only was able to track one short break I took but YMMV maybe it was my Firefox configuration.

Welcome good great 🌹🌹🌹

good

Ok

good to the point app no additional customization bloat, I was looking for simple pomodoro like this which shows time on icon

Tomato Clock de Samuel Jun

THIS is a recommended extension? Really?

Go download "eyeCare - Protect your vision" extension instead.

You can use a slider to set the time you want, and it flashes the icon when done, along with playing the sound of your choice, telling you when to take a break. You can use it for taking a break as well.

This "Tomato" clock is easily surpassed by free apps you can download on Github.

No sound.
Also, it could have had two types/modes of work flow.
Focus and Varia.
Length of both to be set separately.
Focus - for the project work.
Varia - for ongoing errands (mails, replies and so on).

don't miss this for focus
