This table compares the categories that the current version of Privacy Thing supports in each browser; it is not a list of every capability available in Chrome or Firefox. A check mark confirms support for the category, but it does not imply complete spoofing or protection against every fingerprinting technique.

| Geolocation | Supported | Supported |
| Time and locale settings | Supported | Supported with a note |

The current Privacy Thing version for Chrome covers all 13 categories in the table, while the Firefox version covers 11; Client Hints and Battery are the two exceptions.
What the asterisk means
Language and time in Firefox
The optional userScripts permission lets Privacy Thing apply supported settings earlier during a site's first load. Privacy Thing also works without this permission.
WebRTC
Privacy Thing forces relay-only WebRTC connections and applies browser IP-handling controls where available. These safeguards can reduce local and public IP leaks, but the result still depends on the browser and connection setup. They do not change your public IP address.
Dedicated Workers
Privacy Thing applies supported values inside Dedicated Workers automatically. There is no separate Dedicated Workers setting.
Service Workers
Privacy Thing can block Service Worker registration. Blocking is off by default. Enabling it can disrupt offline features, push notifications, and PWAs.
Shared Workers
Native leaves Shared Workers unchanged. Spoof attempts to apply supported values. Strict blocks a worker when Privacy Thing cannot confirm protection before startup.
X-Ray coverage
X-Ray records detected use only within these categories. It does not monitor all network traffic or every action performed by a site.
