 private fun setupGeckoView() {
        val runtime = GeckoRuntime.create(this) // crashes on this line
        geckoSession.open(runtime)
        geckoView.setSession(geckoSession)
        val url = String(Base64.decode(MYURL, Base64.DEFAULT))
        geckoSession.loadUri(url)
        geckoSession.progressDelegate = createProgressDelegate()

This exception will be thrown if there is already an active Gecko instance running. There are many ways to resolve this problem.

Solution 1: Get the default runtime for the given context.

Change your code from

val runtime = GeckoRuntime.create(this)

to 

val runtime = GeckoRuntime.getDefault(this)

Solution 2: Kill the process when exit app by finishing activity, add this code into your activity.

override fun onDestroy() {
    Process.killProcess(Process.myPid())
    super.onDestroy()
}

Solution 3: Only create a new instance if there is no active instance running

private fun setupGeckoView() {
    if (geckoRuntime == null) {
        geckoRuntime = GeckoRuntime.create(this)
    }

    geckoSession.open(geckoRuntime!!)
    geckoView.setSession(geckoSession)
    val url = String(Base64.decode(MYURL, Base64.DEFAULT))
    geckoSession.loadUri(url)
    geckoSession.progressDelegate = createProgressDelegate()
    geckoSession.settings.allowJavascript = true
}

companion object {
    var geckoRuntime: GeckoRuntime? = null
}
