Mac customers can, however, swap to a third-party browser, similar to Google Chrome or Mozilla Firefox, to resolve the safety loophole.

However, on iOS, the problem can be not simply restricted to Safari and can’t be overcome by transferring to Chrome or one other third-party browser. It is as a result of Apple doesn’t permit iOS Web browsers to make use of a third-party browser engine on iPhone and iPad.

Users can restrict knowledge leak by disabling JavaScript on their browser in the meanwhile. But that can have an effect on their expertise as most websites these days use JavaScript to offer fashionable shopping.

FingerprintJS reported the problem to the WebEquipment Bug Tracker on November 28. The flaw nonetheless exists, although.
