Description

On Firefox 64.0 (64bit) on Windows 10 pressing alt+d causes vimium to perform the scrollPageDown action (instead of selecting the URL bar) even if it's bound to just d without the modifier.

Research direction

Start by reproducing the issue in Firefox 64 on Windows 10 with resistFingerprinting enabled, using the alt+d key combination described in the report. Trace the keymapping handling for modifier detection and verify that an unmodified d mapping is not triggered by alt+d; done when the URL bar selection behavior is preserved.
