Title: Permissões 

JShelter requires these permissions:

* **storage**: for storing extension configuration and user options
* **tabs**: for updating the extension's icon badge on tab change
* **webRequest, webRequestBlocking, all_urls**: for modifying JavaScript objects
and APIs on all pages, and for capturing and blocking malicious HTTP requests
* **dns**: for resolving DNS queries in Firefox version of HTTP request shield
* **notifications**: for notifying users on blocked HTTP requests/hosts
* **browsingData**: Fingerprint Detector needs to remove data from any storage
that can save the fingerprint
* **webNavigation**: for deploying wrappers as early as possible to avoid page
scripts accessing unwrapped objects. NSCL use a different approch for this
purpose in Chromium-based browsers. All brosers need the permission to apply
`window.name` protection

jShelter stores all configuration data in the browser or in the user account. It
does not upload any data to our servers.
