Features & Capabilities

Unofficial extension, not affiliated with Anthropic. Claude Token Counter adds a real-time heads-up display directly on claude.ai so you always know where you stand before hitting a limit. What it shows:

Approximate token count for the current conversation, with a progress bar against the 200k context limit Cache countdown timer showing how long your conversation stays cached Session (5-hour) and weekly (7-day) usage bars pulled from Claude's native API, more accurate than the rounded percentages on Claude's own usage page

How it works: All data is processed locally in your browser. The extension reads Claude's own API responses to get precise usage fractions and uses a built-in tokenizer to estimate token counts. No data is ever sent to any external server.

Is Claude Token Counter 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 Token Counter requires a few sensitive permissions. Exercise caution before installing.

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