Firefox prevoius page button reload setInterval

Question

I have a link to a page. The loading is slow and on click event i show a progress bar and run a timing loop with random text. I do this with setInterval. I change the text every 8 seconds.

When the loading is completed, the browser shows the new page. I don't clear Interval because i think the new page doesn't share anything with the previous page.

But, if i click on the previous button on Firefox, it seems to remember the there was an intervarl and it runs it again. In Chrome, the prevoius button seems to reload the page and the interval there isn't. Why Firefox has this behavoiur?

You can see the page here: http://www.demo.tinnservice.com:8090/

I set the interval on click to "Ricerca Avanzata"

This is the html tag

<a class="linkSlow" data-action="archivio" href="/archivio">Ricerca avanzata</a>

This is the javascript code:

function smokeInTheEyes(element){           
            $("body").css("position","relative");
            $("#wait-overlay").addClass("in");      
            var frasi=frasiObj[element.data("action")];
            var i=0;            
            setTimeout(function(){$("#frase").text(frasi[i]).show("400");},1000)            
            var timer=setInterval(function(){   
                i+=1;
                console.log(i);
                if(i==frasi.length){i=0;}
                $("#frase").hide("400",function(){$("#frase").text(frasi[i]).show("400")});                             
             }, 8000);          
    }
    $(".linkSlow").click(function(e){                           
                    smokeInTheEyes($(this));            
                }); 

PS: Frasi is an object with two or more array of strings. The data-action attribute on the clicked tag tell me which array i use to display the random text
