    Open your Firefox browser

    Click on the three dots in the upper right

    Go to Help

    Go to About Firefox

    If it says Firefox Quantum Browser in big letter at the top of the page you are running Quantum

    If it only says Firefox Browser, it is not.

    "Firefox Quantum" was the name used between versions 57 and 69. All versions bearing this name are obsolete now, and should no longer be used. You can find the version information by opening the menu, and going to Help > About Firefox.
