Frequently Asked Questions

  • 1. What is No Service Worker?

    No Service Worker is an extension that enables you to disable service workers on all websites. This addon has two modes to perform the task. The first method is to unregister service workers whenever they are registered. The second method completely nullifies the service worker and websites cannot initiate the service worker in the first place. The second method is rather aggressive and not recommended as some websites may encounter errors. There is also a checkbox in the popup UI to delete the cache. Once marked, all cache items related to the service worker will be deleted. This addon has a whitelist feature to exclude certain domain(s) from No Service Worker. You can add a domain via the toolbar popup or from the right-click menu within the page. If you want to turn off the addon, please open the toolbar popup and then click on the toggle button at the top left corner of the UI.
