Tracking time should be effortless. TMetric’s Firefox extension brings time tracking directly into your browser so you can start timers, log work, and monitor productivity without switching apps. This article walks through what the extension offers, how to set it up, and tips to get the most value from it.

Who it’s good for

Freelancers who need quick timers while browsing client sites.

How to install and set up

Search for “TMetric” and click “Add to Firefox.”
Grant the requested permissions and confirm installation.
Click the TMetric icon in the toolbar and sign in (or create an account).

Basic usage

Click the toolbar icon to open the timer popup.
Choose a project and task, add an optional description, then press Start.
Pause or stop the timer from the popup or the toolbar badge.
To add time manually, open the extension and select “Add time” (or use the web app for bulk edits).

Integration with web apps

When using supported web apps, TMetric can detect tasks or provide inline buttons to start timers directly from the page, reducing clicks and preserving context. Check the extension’s permissions and supported apps list to enable deep integration.

Tips for smoother tracking

Set a default project or task to avoid choosing one each time.
Use descriptive entry notes for easier reporting and invoicing.
Regularly review and correct manual entries in the TMetric web app.
Enable billable flags on client work to streamline invoicing.

Privacy & syncing

The extension syncs entries with your TMetric account so your data is available across devices. Review the extension permissions and TMetric account settings to control what gets recorded and shared.

Troubleshooting common issues

Timer won’t start: restart Firefox and ensure the extension is enabled.
Missing integrations: confirm the web app is supported and you’re signed in.
Entries not syncing: check your internet connection and sign-in status.

When to use the full web app

Use the Firefox extension for quick, in-context tracking. For advanced reporting, team management, and invoice generation, open the full TMetric web app where you’ll find detailed timesheets, reports, and settings.

Bottom line

TMetric for Firefox makes time tracking fast and unobtrusive by placing controls in your browser. It’s ideal for users who need to record work without breaking their workflow, while still relying on the web app for deeper management and reporting.
