Well, this article is simply about recovering from the Mozilla runtime error and fixing the issue whenever your browser throws the error in the future.

    Regarding “Mozilla runtime missing” error using Thunderbird on Windows 10 Pro:
    I have tried the above remedy several times, without any change. I have removed every entry to “Thunderbird” in my registry using RegEdit, and have ensured that Thunderbird is removed everywhere on my PC. I have shut down the PC and then re-booted. I have then installed Thunderbird using the latest version from the Mozilla website. Shut down and rebooted the PC: “Mozilla runtime is missing” appears once more on start up! What on earth is going on???
    Even when I had completely (I thought!) eradicated all reference to “Thunderbird” in my registry, and then doing a subsequent re-boot, I received another error message to say “Thunderbird.exe missing mozglue.dll”!!!
    This is just ludicrous. The actual mail program works fine after I click on “OK” to the “runtime missing” error….
