In order to mitigate this bug, Haddouche has told BleepingComputer that Firefox needs to prevent web sites from download multiple files at once without permission.

This attack has been tested using the latest versions of Firefox Quantum, Firefox Beta, and the Firefox Nightly desktop clients and all of them are currently affected by this attack.
