Koala Zen Firefox

Koala Zen

Every 30 minutes an adorable koala pops up to nudge you to do your habit, then leaves with a short piece of wisdom. Pomodoro or custom rhythms, pause during video calls, progress tracking, built-in koalas and quotes. Stays on your device by default.

Features & Capabilities

Koala Zen brings a little softness to your screen time.

At the interval you choose, an adorable koala appears at the edge of the page. First it nudges you to do the habit you want to build, moving, drinking water, breathing, three push-ups for example. Once you have done it, it comes back to whisper a short piece of wisdom, then leaves in a different, playful way each time, it hops, it rolls, it floats off on a balloon. The koala changes on every visit.

Everything is ready from the start. A library of wisdom quotes, several koalas and movement goals come built in. Keep them, add to them, or replace them with your own.

A break that feels good, not one more thing to do.

What you can do

  • Choose your rhythm, Pomodoro, Deep work, Ultradian, or your own interval from 5 to 240 minutes, in steps of five.
  • Set your habit goals, for example Do 3 push-ups or Drink a glass of water, the koala shows one at a time.
  • Get a piece of wisdom on every visit, from the built-in ones or your own.
  • Confirm each break as done or not, and rate your energy from 1 to 10, on done and postponed breaks alike.
  • Follow your progress in two zones, over the period you pick your habits done, habits postponed, energy and screen time with per-day charts, and an overview with your streak shown as a progress bar toward your record and the link between your habit and your energy. Stats are kept for life on your device, with a button to erase everything.
  • Snooze or pause, later, one hour, the whole day, and catch up the breaks you missed.
  • Stay undisturbed when it matters, automatic pause during video calls and when you step away from the keyboard.
  • Turn on focus mode, a break that blocks the page until the timer ends, for a real pause. Off by default.
  • See your screen time for the day, shown under the piece of wisdom and under the gentle nudge. It resets at midnight in the time zone you pick, Zurich by default or your browser's.
  • Make the koala yours, add up to 18 of your own PNG or animated GIF images, write your own quotes and your own goals.
By default, nothing leaves your browser. Your settings, your progress and your images are stored locally. No account, no analytics, no tracking, no ads. The one exception is an optional backup to your own Infomaniak kDrive, off unless you turn it on yourself in the Data tab.

Give yourself the few seconds that change a day.

Is Koala Zen Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Koala Zen requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Koala Zen is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
