A small Firefox extension that makes missed time entries obvious.

It converts Tracky sessions into 5-minute slots and marks gaps as:

• ❌ (unbooked)

So you can immediately see where time entries are missing.

1. Open about:debugging#/runtime/this-firefox
2. Load manifest.json as a temporary add-on
3. Open Tracky (or example.html) and use the Tracky gaps toggle
