Auto-Clear Site Data

Take ultimate control of your digital footprint. Auto-Clear Site Data is a powerful, intelligent, and container-aware extension that automatically clears a website's data (cookies, local storage, indexedDB, Cache, Service Worker) as soon as you close its last tab.

It's the "set it and forget it" solution for browser hygiene, privacy, and performance.

The process is smart and simple:
1. You close the last tab for website.com (e.g., in your "Personal" container).
2. A configurable timer (e.g., 30 seconds) starts.
3. If you don't re-open the site in that container, the extension automatically clears its data.
4. Your other containers (e.g., "Work") are completely unaffected.

Key Features

📦 First-Class Firefox Container Support
This extension is built from the ground up for Firefox Containers. It maintains separate exemption lists for each container (Work, Personal, Shopping, etc.). Clear google.com in your "Personal" container while keeping it logged in for "Work".

⚙️ Granular Data & Exemption Control
You have total control.
* Choose What to Clear: Select which data types you want the extension to manage (Cookies, Local Storage, IndexedDB, Cache, Service Workers).
* Per-Rule Exemptions: Don't just whitelist a site. You can choose to keep Cookies (for login) but automatically clear Local Storage and Cache for that same site.

🧠 Intelligent Global Data Handling
The extension understands that Cache and Service Workers are shared globally. It will intelligently defer clearing this data if you have the same website open in any other container, preventing conflicts and ensuring other tabs don't break.

🖱️ Powerful Popup Interface
Click the toolbar icon for instant control:
* See the current site's status: Fully Exempted, Partially Exempted, or Not Exempted.
* If not exempted, add a new rule with a smart slider (e.g., www.example.com vs. *.example.com).
* If already exempted, instantly edit which data types are saved for that rule.
* See detected 3rd-party frames and scripts and add rules for them directly.

🛡️ Advanced "Deep Clear" Engine
Go beyond the main domain. When a site is cleared, the extension can also find and clear data from:
* Sub-Frames: Automatically clears data from embedded cross-origin iframes (e.g., trackers, ad services).
* 3rd-Party Scripts: Detects 3rd-party scripts (e.g., analytics) and adds their domains to the clear queue.
* Related Domains: Scans cookies and parent domains to find and clear data from associated hostnames (e.g., clearing cdn.example.com when you close example.com).

✨ Smart & User-Friendly
* 2-Step Navigation Delay: Prevents clearing data if you navigate A -> B and quickly hit the back button. It waits for you to navigate A -> B -> C before clearing A.
* Redirect Catching: Catches and clears data from "ghost" pages like tracking links and URL shorteners that you only visit for a split second.
* Clear on Startup: Cleans up any sites left over from your last browser session.
* "Clear Now" Button: A force-clear button in the popup lets you bypass all checks to wipe a site's data immediately.

Privacy First

All processing is done 100% locally on your device. Your settings, exemption lists, and browsing habits are never transmitted, shared, or analyzed.
