    To control double click problems, i built this function, basically for every function you want to protect against the user clicking too fast, double click etc.. you call this function instead and define the timing range of release of the function. This is usefull to avoid API or endpoint calls that makes no sense or would be repetitive, or abusive in some cases.

    The method_name parameter is just any label you desire, just in case you want to check the prevented array lists with console.log(runnning_methods);

    Usage example:

                      
    var runnning_methods={};
    function preventQuickMethod(method_name,callback,delay_time){
    		if(!delay_time){var delay_time=500;}
    		if(runnning_methods[method_name]==1){return;}
    		setTimeout(function(){ runnning_methods[method_name]=0; console.info(method_name+" released");},delay_time);
    		runnning_methods[method_name]=1;
    		callback();
    }
      
      
      function nextpage(){
        preventQuickMethod("dismissSlot",function(){
            document.getElementById("btn").innerHTML="fired at "+Date.now();
        },1000);
    }
                        
    <button onclick="nextpage()">Fire!</button>
<span id="btn" >EHHEHE</span>

    Move your clearTimeout above the alert

    clearTimeout(timer);
popupAc(id);

    PS: I might be wrong, just guessing, not having firefox here..
