    Firefox won't start after updating Win 10 Pro to version 20H2


    I updated Win 10 Pro to version 20H2 and now Firefox will not start. No error message; no appearance in Task Manager. Here's what I've tried to no avail:

    1) Uninstalled and reinstalled Firefox several times, including manually removing all remaining Firefox files (including my profile folder) after uninstall.

    2) Tried to start Firefox with administrative privileges.

    3) Clean booted Windows and tried to start.

    4) Turned off Windows Firewall and tried to start.

    5) Tried to start in Windows Safe Mode.

    6) Firefox will start and run normally when installed into a Windows Sandbox on the same computer that won't start Firefox in Win 10 version 20H2.

    7) Extensive Google searches to try to find a solution.

    Oddly, Microsoft Edge will not start either, but Chrome starts and works normally.

    :)

    Yes I am using a genuine apple cable and tried your method but still having issues . The device connects and all looks fine for a few minutes then it drops connection then reconnects and repeats this behaviour so I've gave up .see attached images.
