For background information see [_"What's CNAME of your game? This DNS-based tracking defies your browser privacy defenses"_](https://www.theregister.com/2021/02/24/dns_cname_tracking/).
The setting will be disabled on platforms not supporting this feature. It's currently supported only on Firefox.
In some edge cases, it might be necessary to disable this setting to prevent network-related issues. For example, [_"Pages load slowly when uBlock Origin is installed"_](https://bugzilla.mozilla.org/show_bug.cgi?id=1694404#c5), which occurred when funneling network requests through a proxy.
The setting will be disabled on platforms not supporting this feature. It's currently supported only on Firefox.
**Important note when using extension-based proxy service:** Extension-based proxy services are often done on-the-fly through a [browser API](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/proxy/onRequest), and in such case uBO's own DNS queries to uncloak canonical names will **NOT** be caught and proxied by an extension-based proxy service. So you may want to disable this setting when using an extension-based proxy service.
