Service Worker Notifier од ToHub

Service Worker Notifier gives you control over which websites may register service workers in your browser.

What it does
When you visit a page that uses service workers, a small notice appears in the bottom-right corner showing how many workers are registered and on which host. You can then:

• Unregister them with one click — this also adds the host to your Exceptions list.
• Close the notice for the current session if you don't want to act right now.

Once a host is in the Exceptions list, every service worker on that host is removed automatically on every visit — no notice, no prompts. This is useful for sites that quietly re-register their workers.

Features
- Per-host exception list with subdomain coverage (adding example.com also covers sub.example.com).
- Automatic cleanup on every visit for exception hosts.
- Manual cleanup tool: force a cleanup for any host at any time.
- History of every removed or blocked worker, with host, count and timestamp.
- Export the history as JSON or CSV.
- Light and dark theme, following your system preference by default.
- Multi-language interface (English and German included; more can be added).

Permissions explained
- storage — to save your exception list, history and settings locally.
- tabs — to read the URL of the active tab so the popup can show the current host.
- browsingData — to remove service worker registrations for the hosts you block.
- <all_urls> — to detect and block service worker registration on any website.
