Habit tracking apps have one friction point: you have to open them. For a habit you are logging every day, that opens a motivation gap — the more steps between the action and the log, the more likely you skip it.
Habit Tracker New Tab for Firefox solves this by putting the grid in the browser.
How it works
The extension replaces the Firefox new tab with a monthly habit grid. Each row is one habit. Each column is one day of the month. Click a cell to mark a habit done for that day.
The grid is there every time you open a new tab. You do not open an app to log a check — you open a tab you would open anyway.
Habit Tracker New Tab — Firefox Add-ons
Setup
- Install the extension
- Open a new tab
- Add your habits by name
- Start clicking
No account, no signup, no configuration beyond naming your habits.
Data storage
All data is stored locally in Firefox's extension storage. Nothing is uploaded, synced, or backed up to any server. The data is on your machine only.
This means no account to manage, but also no sync across devices. If you use two computers, you would need to maintain two separate grids.
Who it works for
Good fit:
- People building daily routines (exercise, reading, language practice, journaling)
- Anyone who already has Firefox open most of the day
- People who want a lightweight tool without subscription overhead
Not a good fit:
- People who need cross-device sync
- People who want detailed analytics, streaks visualization, or social accountability features
- People who want reminders/notifications
Comparison with dedicated apps
Apps like Streaks (iOS), Habitica, or Notion templates have more features: reminders, statistics, sharing, gamification. The extension has none of these.
What the extension has: zero friction for the daily check-in. For the core behavior of "open browser → see grid → click done," it is the fastest possible path.
