## Description

Track your Gemini usage: The Limit Watcher shows how much of the current 5-hour window and weekly limit on Google Gemini has already been used. The extension supports the displayed Gemini plans Free, Plus, Pro, and Ultra.

<ul><li>Color-coded ring icon with a percentage value in the toolbar</li><li>Automatic switching between the 5-hour window and weekly limit</li><li>Popup with both progress bars, reset time, and detected plan</li><li>Firefox sidebar with a live countdown</li><li>Optional movable and resizable overlay inside Gemini Chat</li><li>Manual updates or automatic updates at a selected interval</li><li>Support for multiple Google accounts through Gemini paths such as <code>/u/0/</code> and <code>/u/1/</code></li><li>Separate usage data and plan information for every detected account</li><li>English and German user interface</li></ul>

The extension uses an already open tab on <code>gemini.google.com</code> to read the usage information provided for the signed-in account. It primarily evaluates the usage data loaded by Gemini directly. If the plan cannot be identified reliably but valid usage limits are available, Free is shown as a fallback.

At least one matching Gemini tab must remain open for manual and automatic updates. When multiple Google accounts are used, their data is stored and displayed separately according to the respective Gemini account path. No additional or minimized helper window is opened.

Usage data and settings remain stored locally in the browser. The extension does not transmit usage information, chat content, or login credentials to external services. The Google account must be signed in within Firefox.

<ul><li><code>storage</code>: stores settings and the latest retrieved values locally</li><li><code>tabs</code>: detects open Gemini tabs and the currently active account</li><li><code>alarms</code>: performs scheduled updates and display switching</li><li>Access to <code>gemini.google.com</code>: reads only the Gemini data required for usage display and plan detection</li><li>Sidebar permission: provides the Firefox sidebar with usage information and a countdown</li></ul>
Gemini Limit Watcher is an unofficial community project and is not affiliated with Google. Changes to Gemini, its internal interfaces, or its page structure may temporarily affect detection.
