  Firefox has become very slow. It takes a lot of time to load any website. I reinstalled FF but the rest of the problem.
  As a test, I downloaded Chrome and it is much faster.
  But I love FF and would be very happy if you can help me solve this problem.

  Hi Reos,

  When you reinstall Firefox it always uses your old profile with all the old things that you had. That said, you're lucky, there is a new feature that lets you "Reset" of Firefox. This will remove some of the pieces that might cause problems while it keeps your bookmarks and other important things safe.

  Check it out and let me know if it works: Refresh Firefox – reset the parameters and modules

• Firefox has becomes slow and unresponsive after that I tried to install the addons (not installed)?

  I recently format my computer and reinstall windows 7, since it was the only way I know of to solve the problem with Firefox (I already had this problem too). I download the latest version of firefox 33.0.2 and install it. This version was super fast. But becomes slow and unresponsive when I tried to install the Add-ons. I visited the official site of firefox and searching for addons, when I tried to install addons, Firefox crashed. Therefore, it has becomes quite slow and cannot restore previous sessions. Even to type my email address, it takes more than 5 minutes and reacts more frequently (after typing each letter).
  I want to know if this is due to some viruses, or this version of firefox is not "stable".

  Hey there,

  We are sorry to hear that Firefox crashes. To better help you, please follow the steps below to provide us with crash IDs to help us learn more about your accident.

  1. Enter Subject: hangs in the Firefox address bar and press ENTER. A list of submitted Crash reports will appear, similar to the one shown below.
  2. Copy the 5 most recent report ID begins with bp - and then back to your forum question but that stick in the box of "Post a response. (Please do not take a screenshot of your plant, just copy and paste the ID image below is just an example of what your Firefox screen should look like)

  

  Once you have done so, you could try the Firefox Safe Mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that disables certain parameters, disables most Add-ons (extensions and themes).

  If Firefox is open, you can restart Firefox Safe mode in the Help menu:

  • In Firefox 29,0 and above, click on the menu button

    

    click Help

    

    then select restart with disabled modules.

  • In previous versions of Firefox, click on the Firefox button in the upper left of the Firefox window and click help (or click on help in the Menu bar, if you do not have a Firefox button) and click on restart with disabled modules.

  If Firefox is not running, you can start Firefox in Mode safe mode as follows:

  • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
  • On Mac: Hold the option key during the startup of Firefox.
  • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
    (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

  When the Firefox Safe Mode window appears, select "start mode safe."

  

  If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. Please follow the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

  I hope this helps!

• Why firefox has become bloated and lazy like IE?

  I tried like hell to stick with firefox, but it became useless.

  Installation of costs, on a new installation of operating system on a PC with 8 cores@3ghz and 32 GB of ram, and firefox is STILL SLOW!

  More than 10 tabs == random crash for a few seconds / minutes
  Have more than 5 tabs and close one that it blocks a few seconds to a minute.
  Have more than 10 tabs open, select "Close other tabs" after the tabs, FF hangs for 30-90 seconds.

  After the closure of the tabs, CPU utilization pulls up to this core... I say for this kernel, because the limit of mozilla firefox for one heart, which wouldn't be so bad, except EVERYTHING ON THE SYSTEM HANGS waiting for THAT ONE CORE to CATCH THE FUCK UP!

  Add on top of that firefox looking more and more like the chrome... I mean.. Firefox is essentially like having the version slow, delayed, shit smell of chrome...

  PLEASE GO BACK TO WHAT MADE YOU FAMOUS!

  A light and fast browser.

  NOBODY WANTS OR NEEDS ALL THAT USELESS GARBAGE YOU KEEP SHOVELLING AWAY!

  Here's an idea, before avant d' ajouter to add more code buggy nonsense that serves nothing real other than to make you look more like a bastardised version of chrome, why don't you actually fix crap buggy, slow garbage code have already set you up?

  STOP TRYING TO BE LIKE THE CHROME! IF I WANTED CHROME FUCKING, I HAD TO INSTALL IT!

  If the next version of Firefox is nothing else than to fix the many problems causing slow performance and high CPU usage, I'll be moving to chrome and leave Firefox and Mozilla to continue its business of a slow and painful death walk down.

  @the-edmeister thanks for the typical canned answer, I am pleased to see that copy - paste works always.

  Canned responses do not work, because the situation is based on a new installation of the operating system and a new installation of firefox.
  All the drivers on the system is new and up-to-date.

  I ALWAYS run through the basic troubleshooting list. If I had found a solution for poor performance and hogging CPU memory/crappy, I him have not posted here.

  @jscher2000
  Thanks for the link, but I had already tried it, work with no joy.

  As for the rest of the answer, I have a few comments and questions:

  Statement: "Mozilla's mission is to drive the web forward, which is to introduce new technologies constantly in Firefox."

  Comment: Change the GUI to work and look like Chrome is not new and innovative. It is simply duplicating someone else's ideas.

  Statement: "at the same time, developers constantly working to improve the efficiency of memory."

  Comment: since when? Over the years, whenever FF has "updated" the memory usage has increased. On rare occasions, it has also introduced memory leaks, or attempted to hide or split to its own use of memory in the secondary threads... plugin-container for a good idea, is an example that has been poorly implemented.

  Statement: "because the browser code is open source, others have used it to create products that look more like older versions of Firefox, or gathered for 64-bit systems, etc..". You can check those and decide if they are more productive for you than the official version. »

  Question: Where might these alternatives. Simply Googling turns a myriad of other browsers, Chrome for most of the results. Versions of firefox based very little I could find are the pale Moon and waterfox.
  Others are based on the FF are for most * nix flavors or specialized for users of niche such as cat and iceweasle for gnu and debian ice respectively, and wyzo based on niche media downloads.

  I understand that Firefox is open source, and if I had the time team, Fund and development to devote to creating a browser standard, basic, no frills, using their source, I would have already.

  My problem is not with Firefox itself, but the struggle continues Mozilla comply Firefox for chrome UI, while gradually adding bloat, instability and some "features" unnecessary which are not needed or requested by users.

  I get that Mozilla tries to innovate. But adding bloat and tracking features of data or features that cannot be used unless the tracking data is enabled is a huge slap in the face of almost all those who have started using firefox because it objected to these measures implemented in other browsers at the time.

  The entire reason why firefox became so popular was because it worked, was quick and did not use all of the system cpu and ram. Why? because at that time, it had all the bells, whistles, gadgets, door knockers, the banana seat, ape-hanger handlebars and a chrome-plated stand... Remove all trash, and the browser would be more likely to cut its use of CPU and memory in two, if not more.

  And Yes... This has turned into a feedback session.
  No, I didn't intend to let him be.
  No, I will not create a survey of 'feedback '... I've done done several times over the years, and as is typical of mozilla, they simply ignore it and do the opposite.

• 19 of Firefox has become incredibly slow since Windows 7 update 27/02/2013

• After the upgrade to 6.0.2 6.0.1 Firefox has become laggier in terms of response time.

  For example, new tabs open/close after a break of the half second. I noticed that when I do that, the spikes of CPU activity at 25% and dies down. Sometimes in typing text will pause as well. His behavior is as if he was mired with a memory leak.

  If anyone still has problems, I seem to have much better results after uninstalling the toolbar of Facebook.

• Firefox has become very slow for the last days.

  I didn't something for my system. I always clear the cache. I ran antivirus/malware and nothing was found. I've tried Chrome and it works very well.

• A few days ago, Firefox has become too big for my screen. I have to move the slider at the top to get the bar menu at the show and then there only if I hold the cursor there. Very annoying.

• With Firefox 9.0.1 an application using a JavaScript confirm command does not display the message. Blocker is disabled for the domain of the application.

  Application is written in php and javascript. Clicking a button triggers a javascript confirm dialogue. Since upgrading to Firefox 9.0.1 confirmation dialog box does not appear. Trainer first set to allow the full domain of the application, then off altogether. JavaScript is enabled.

  It turns out that Firefox has become a little more picky about the standards that IE. (Imagine that!) Code created the entries of type = 'text' hidden, then calls a javascript function and the values passed in the entries hidden as parameters. The original code just pass the name of the entry as a variable. Then, the Firefox console complained that the variable was not declared. Once I spent the variable.value, then the error disappeared, Firefox has been happy, does not break IE, so I'm happy.

• Hi, while writing an email online using Firefox 3.6.3, I was using one of the "CTRL + left arrow or right" to move the cursor on the text. I must have pressed some other key because the screen has become huge - and I can't scroll vertically or horizont

  Hi, while writing an email online using Firefox 3.6.3, I was using one of the "CTRL + left arrow or right" to move the cursor on the text. I must have pressed some other key because the screen has become huge - and I can't scroll vertically or horizontally, which makes the pages of Mail of Hotmail impossible. I have connected since using the Explorer MSFT and it works very well. This problem occurs only on the page of Mail of Hotmail Live not on the home page or other.
  Could you please let me know if there is a problem with Firefox, or if you have any advice on how to restore the appearance of Hotmail in Firefox?

  This has happened

  Just once or twice

• Firefox has started to freeze on the opening and hangs / freezes frequently during use.

  Firefox has begun to open very slowly [very]!, as well as to crashing and freezing during use. What's happening on all my three machines, two running Win 7 and the other win 8.
  I tried refreshing and disabling, but to no avail hardware acceleration.
  Now it seems to freeze on opening and takes a minute or two to become sensitive, or not at all.
  When I look into during a freezing Task Manager, I see the Firefox process use 35 to 50% of memory [I have 8GB, 12GB, and 16GB] and up to 50% of the CPU resources.
  Everything was fine until the last two weeks.
  In addition, last month, I noticed an almost permanent error on the status bar message - ' Sync has encountered an error during synchronization: unknown error. " Synchronize automatically retrying this action. »

• Why Firefox has disabled the only version of Flash (10.1.53.64) my computer can use? (Mac PowerPC G5) Help!

  Why Firefox has disabled the only version of Flash (10.1.53.64) my computer can use? (Mac PowerPC G5) Help!

  Your computer hardware has arrived at the stage where most of the software needs resources your machine cannot provide because it's too old. You have a few choices.

  1. Get new hardware that can handle the latest software
  2. Use a different operating system, like Linux (which is free)

  I rehabilitated an old G5 recently and it runs very well in the latest Firefox. I put Lubuntu on the machine instead the MacOS. Lubuntu (pronounced Loo-boon-two) is sort of a Ubuntu lite - a user-friendly version of Linux. There are many applications of your choice, and everything is free.

  You can also use the Ubuntu greediest in resources and a little more user-friendly, also free, but you can be more pleased with the performance of Lubuntu instead.

  The PowerPC, I did this on was one of the old blue Bondi ones. Firefox 8 had no problem to start on it at all and has all necessary plug-ins for video, audio, etc... I gave him a church and it works well for them.

  You can download older versions of Firefox, but you'll just open to security problems if you do.

  FYI: The Mac operating system is based on Linux.

• Firefox has disabled arbitrarily IDM cc which worked fine for months, how can I reinstall it I won't stop using Firfox if I can't use IDM.

  Firefox has arbitrarily disabled the IDMcc even if I used it several times a day for months with no problems. I want to reinstall IDM and use it. If I can't I will stop using Firefox and come back to IE. I prefer to stay with Firefox, but I won't be using a browser that doesn't let me use IDM which worked very well.

  == I reloaded Firefox I told what IDM has been disabled
