Every productivity system I tried worked for two weeks and then collapsed. The issue is usually not the system — it is the friction of maintaining it. If your habit tracker lives in a separate app, you open it, log a check, close it. It competes for attention with everything else.
What if it was just there?
The case for a browser-native habit tracker
You open a new tab dozens of times a day. If your habit grid is on that page, you are always a glance away from your current streak. You do not need to open an app, sign in, or navigate anywhere. It is ambient.
That is the idea behind Habit Tracker New Tab.
How it works
Each new tab shows a monthly grid — one row per habit, one column per day. Click a day to mark it complete. The grid shows your streak at a glance. No weekly reports, no gamification points. Just a grid.
The habits you track are whatever matters to you. Exercise, writing, reading, medication. The extension does not prescribe a system.
Why local storage matters for habit tracking
Habit data is personal. What you are working on changing about yourself is not something that needs to be in a cloud database somewhere. Habit Tracker New Tab stores everything in Firefox's local extension storage. Nothing leaves your browser.
This is also why it is fast. No API calls, no sync latency. The grid loads instantly.
The streak mechanic
Streaks are motivating but fragile. A missed day breaks a streak, which can be demoralizing. Habit Tracker New Tab shows the streak, but the grid is the primary artifact — a month of data is more informative than a single number. You can see patterns even when streaks break.
