Firefox Support Forum

I updated to FF 17 about an hour ago and since then the back & refresh buttons no longer work. I do not have McAfee site advisor or tab mix plus on my browser.

How do I fix this? It's making my browsing VERY difficult and I have work to do.

The error message from Firefox is: The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.

Win7 on DELL XPS9000-----64bit. Successfully run IE, Safari and Chrome. Download Mozilla Firefox 17 (and other versions before 17) Firefox home page loads----------but nothing else loads! i.e., can not access other pages, such as nbcnews, etc.----Nothing.

My laptop runs firefox nicely; I like firefox--------but I can't wait for the thing to never load.

any suggestions will be appreciated.

This is more of a criticism than a bug report. It seems that whenever I run Firefox, there is an issue. I can't tell you how many computers I've been to where:

• Firefox complains that it is out of date.

I get it, updating software is hard, but don't burden me with the issue. Updates should be quiet and seemless.

• Firefox needs to inform me about my rights.

99.9999999999% of users don't know or care about this.

• Firefox is unhappy that it's not my default browser.
• Firefox babies the user when downloading extensions.

Adding a 3 second timer to your install button doesn't make the user choose safer decisions. It just makes me impatient. What's the justification for this delay? Do you have proof that you've curbed malicious behavior?

I just want to run Firefox and not be burdened with all of this. Don't bother me with updates, don't treat me like a baby, just get out of the way so I can get to work.

Thank you.

trying to use firefox, take forever jsut freezes and on the bar at the bottom keeps saying transferring data, have closed all logins but the same. how do I go back to earlier version to 16, this is just total crap. Can not even open facebook

Firefox constantly crashes and it's getting worse. It seems to be more and more frequent. Also, before it crashes it often spends hours or longer hanging, lagging and using excess memory (often 1-1.5g of ram).

I've attached the last 3 crash details below (from about:crashes).

When I go to www.sprintpcs.com, the screen does not load all the way and I cannot check my minutes used; number of text messages used or any other such data. If I switch to IE or Google Chrome, I do not have a problem checking the aforementioned. This is a recent problem since upgrading to Firefox 17. Please help as I really like using Firefox over IE and Chrome.

Last night, a problem began occurring when I launched Firefox. Every time I open my browser, it launches the previous session from when I last closed it. The problem persists despite many attempted fixes.

The option "When Firefox starts" is set to "Show my homepage". I've restarted my computer and ended the process, so I know that Firefox doesn't have a window or process still running.

I've tried deleting sessionstore.js and sessionstore.bak but that only works once and then it goes back to opening whatever tabs and windows I had open when I last closed Firefox. I've reinstalled Firefox with no results and cleared all private data except history and it didn't do anything.

I didn't install anything or update any add-ons or extensions, but it just started occurring after a normal browsing session. I've tried to find other solutions, but nothing I have found has worked. Does anyone have any new solutions or suggestions?

This problem started about a month ago and I only just got around to trying to fix it.

Symptom: No sound on some but not all videos on Youtube.

Firefox 16 and Firefox 17 Tried with Flashplayer 11.5, 11.4, 11.2, 10.4. It happens in safe mode. It happens even when all Add-ons are disabled.

It does not happen in Chrome.

I'd be very grateful for suggestions on how to troubleshoot this. I've already googled extensively and none of the suggestions I found helped.

this is really to report what occurred this morning.

since the update to v 17 Firefox would not run d/loaded the new version twice (uninstalling between) but to no avail - the program would not open although Task Manager shows the process running.

have re-installed v 15 so I have a browser.

lack of a way to report such problems is a weakness which needs addressing

So. I was a pretty loyal chrome user since it's Beta. Noticed that it used a lot of processes for each tab I had open.

I didn't like that.

So I installed Firefox.

Noticed that Firefox is very slow. I mean VERY SLOW. Youtube videos? 5+ mins to stream a 3 min video. If I am lucky.

Gmail? Last attempted login took 5 refreshes, and still took over 3 and a half mins before it finally let me in.

Tried these same things on Chrome. Got into Gmail in under 5 seconds. Youtube videos? Don't even need to let it stream ahead. Played the same video flawlessly.

Tried everything in the troubleshooting to make this slow issue go away. Don't like Safari, hate IE like it will give me the plague. Opera is... meh. Okay I guess. Marginally better than Firefox at this point. I'm sorry to say, I am going back to chrome. None of your solutions fixed the issues, or even offered marginal performance increases to warrant holding out hope that there may be something just around the corner to make this a great browser again.

So. With that said, Firefox, we were once good friends, but like a business investment, it's time to cut my losses and move on to bigger and better things.

Ciao.

In a site I have a box, with a list of values, but in version 16 and 17 I can´t open that. Version 15 and bellow didn't have any problems to open the list of values.

I've noticed that my Firefox using really extended amounts of RAM (600 MB or so). I have tried everything what is suggested on Knowledge base, disabled plugins & addons, started in safe mode, etc etc, but problem still ocurs, even if I have opened only two tabs. But when I have closed gmail tab, Firefox's RAM usage jumped down to 100 MB. When I have opened it again, RAM usage will become something around 600 MB again, so it seems to that gmail is causing my problems.

Why gmail consuming so much RAM in my computer? Is there any way to get rid of it?

Sinds 1 week werk ik met Windows 8. Alles werkt erop, ook firefox, alleen krijg ik in het menu allemaal raren teksten en kleur problemen. Deze problemen doen zich ook op bepaalde websites zoals Raptr.com voor. Dit probleem heb ik alleen met Firefox. Bij andere brouwsers heb ik nergens last van. Bij 16.0.2 viel het nog wel mee, maar bij 17 is het erger geworden in plaats van beter.

Wat kan ik doen om Firefox toch werkend te krijgen in Windows 8

I'm using an onload eventlistener to call a script which increases the value of a variable. I need to get the variable's value before I increase it. Safari and Chrome (Webkit) give the right result but Firefox always alerts "0"... To be clear: Firefox also alerts "done" which means it gets the job done but it does NOT alert the right value before I increase it!

This is my Script:

var obj = {

   build: function() {
       var progressCount = 0; 
       var otherFunction = function(number) {
               alert(number);
       } ;
       var finalFunction = function() {
               alert("done");
       } ;
       var progress = function() {
               alert(progressCount);  // very important line!
               progressCount++;
               otherFunction(progressCount);
               if (progressCount == ARRAY.length) {
               finalFunction();
               }
       };
       ARRAY=document.getElementsByClassName("picture");
       for (var i = 0; i < ARRAY.length; i++)
       ARRAY[i].addEventListener("load", progress);
   }

}

obj.build();

What else could I try? Thank you very much!

Please find below jsfiddle for reference

jsFiddle for Mozilla Firefox -- http://jsfiddle.net/ranu_mandan/EBmdf/

Javascript (FF)

var c=document.getElementById("myCanvas");
var ctx=c.getContext("2d");
ctx.font="30px Arial";

var counter = 0;
c.addEventListener('DOMMouseScroll',function(event){

    draw();

    return false;

}, false);

function draw(){   

   var j = ++counter;
   for(var i = 0; i < 10000; i++){
    ctx.clearRect(0, 0, c.width, c.height);
    ctx.fillText("Hello World " + j ,10,50);
   }

 }

jsFiddle for Google Chrome -- http://jsfiddle.net/ranu_mandan/mk5rZ/

Javascript (Chrome)

var c=document.getElementById("myCanvas");
var ctx=c.getContext("2d");
ctx.font="30px Arial";

var counter = 0;
c.addEventListener('mousewheel',function(event){

   draw();

   return false;

}, false);

function draw(){   

  var j = ++counter;
  for(var i = 0; i < 10000; i++){
   ctx.clearRect(0, 0, c.width, c.height);
   ctx.fillText("Hello World " + j ,10,50);
  }
}

HTML

<!DOCTYPE html>
<html>
<body>
<span>Scroll on below canvas</span>
<br/>    
<canvas id="myCanvas" width="600" height="100" style="border:5px solid #d3d3d3;">
Your browser does not support the HTML5 canvas tag.</canvas>
</body>
</html>

Now try Scrolling fast using mouseWheel on canvas on above fiddles , you will find numbers are skipped in Firefox , whereas Google Chrome renders smoothly without skipping the numbers.

How to make rendering similar to Google Chrome in Firefox browser ?

my email does not display properly since it was updated today, I've even tried uninstalling and re installing. email will come up but off to the left us small box appears with the contents of the email which is to small to even read.

I cannot download pdf or other documents. This is a brand new problem; I've been using Firefox successfully for years. I can download documents in Safari. I have the latest version of Firefox and also Adobe. I also cleared out all older versions of Adobe and reinstalled the most current version of Firefox
