Features & Capabilities

Claude Usage is a lightweight Firefox extension that lets you monitor your Claude usage without repeatedly opening the Claude Usage settings page.

The extension displays your current Claude session usage directly in the Firefox toolbar and provides a compact popup showing:

• Current session usage percentage • Current session reset time • Weekly all-model usage percentage • Weekly reset time • Automatic background refresh • Manual refresh • Light and dark interface modes

Claude Usage uses your existing Claude login in Firefox to retrieve usage information directly from Claude. No Claude API key is required.

The extension does not read your conversations, prompts, projects, files, or message contents. It does not include advertising, analytics, telemetry, or third-party tracking.

Usage information is processed locally by the extension and is not sent to the extension developer or any third-party analytics service.

Important: Claude Usage is an independent browser extension and is not affiliated with, endorsed by, or produced by Anthropic.

Is Claude Usage Indicator 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.

Claude Usage Indicator requires very minimum permissions.

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.

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