Its awesome.
One more feature suggestion:
Have option to automatically start it with browser

1. Lots of bugs, including one with a red exclamation mark. We are not developers and do not know what this means.

2. Developer makes it extremely difficult to report this to them directly. Their so-called "contact" information is a link to their GitHub account.
(a) GitHub is totally confusing to us. We are not familiar with it. As per 1, we are not developers.
(b) We do not see any place to leave a message. Nor can we find any GitHub instructions as to whether GitHub is an appropriate place to.
(c) It requires the rigamarole of taking out a user account. No, we are not going to go to all that trouble.

3. One star for the above.

4. Uninstalled.

Das ist so brauchbar. Danke!

i wish it could count how many x last pomodore (x) times I have done....and show me the z( duration z or 15 minutes) to take a long brake, each 4 (x + y) pomodore times....thx for ur addon

The countdown is not always what I had set to be

to see the remaining minutes in the icon is my favorite feature. Great work.

is gone very well but not have the option of loop with alarm tone :c

Good extension.

Would be nice to have manual pause.

Does what it says on the tin - simple timer with adjustable timing & breaks, loops automatically, and customizable sound.

Shoutout to the developer for prioritizing the fewest possible permissions required for an add-on, and being responsive with updates!

It does exactly what it is supposed to do and it does it right. One little issue I have under firefox 74.0 on windows 10 is that I have to click on the icon twice for the panel to show. I hope it's just a temporary glitch.

Update 04/09/2020: The glitch seems to be resolved! But now I've noticed that sometimes the bell rings and sometimes it doesn't. Tends to happen when I've had my laptop/browser running for a long time (i.e. days between restarts) but plenty of sleep cycles.

I love the bell, ringing when to continue working and when to pause

A good basic pomodoro timer. However I do not like that it automatically goes into breaks (I couldn't find a way to change this either) because I frequently will finish up what I was doing past the work time and with this timer, that means I don't get the full break.

Minimalistic design. Does what it should, no more.

Muito bom tem som de sino fica ainda mais interessante de tiver gráfico do rendimento

Does what it says on the tin, the only 2 things preventing a 5 star rating is the sound - it's exactly like my doorbell! and that it doesn't interupt your browsing experience well enough to notify you (like another similar timer does) which is perfect for situations when you cannot have sound
