Firefox has a delayed response time and is laggy and slow. It has a delayed response time.

I typically have 3-4 windows open (use a compaq laptop and windows 7) and there is a "freeze" before firefox responds and it's laggy and slow.

Have you disabled hardware acceleration?
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]

    Every time I TRY to start firefox 18-19 I get an error message : "Firefox has stopped working" - "close the program and check online for a solution" - or - "close the program" this happens TWICE every time I try to start firefox. Eventually after a random number of tries firefox will start normaly.

    I have tried a Clean reinstall but it did not help.

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.

    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #*'''Windows:'''
    #**C:\Program Files\Mozilla Firefox
    #**C:\Program Files (x86)\Mozilla Firefox
    #*'''Mac:''' Delete Firefox from the Applications folder.
    #*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

    Firefox has crashed numerous times on me tonight, and I keep getting an unresponsive script error (Script: chrome://devany/content/main.js:254) regardless of what website I'm on. NoScript will not block this script, and it's popping up with an increasing and alarming frequency. It's completely crippled my Firefox, and getting the a large enough window between unresponsive script warnings to get the Troubleshooting Information from Firefox took me a good 20 minutes. It's a very persistent script. I've already re-installed Firefox and restarted my computer, and scanned for viruses/malware. I'm on a Mac, if it makes a difference.
    == This happened ==
    Every time Firefox opened
    == Tonight. I can't say what site I was on, though I first noticed it on DeviantArt and thought it was their new layout producing problems. ==
    == User Agent ==
    Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_8; en-us) AppleWebKit/531.22.7 (KHTML, like Gecko) Version/4.0.5 Safari/531.22.7

    yay, I had this same issue, and I too browsed deviantArt and also have got Deviantanywhere add-on installed. : D
    I'm so glad that You've found a solution and shared it with us.
    I was really getting worried that I'd done something to get malware installed on my 'puter. *Phew* !!
    I'm going to disable DeviantAnywhere after I post this and hopefully this will be fixed for me too!
    I actually hadn't kept my firefox up to date. but.. *shh...*
    I updated it and after I did, it told me that there was a script running that was not responding. : )
    yay for FireFox~

  • Why firefox has slow response when i 'm saving pictures to hard disk?

    I have windows 7 64 bit and Mozila firefox ver. 17.0.1. I have the following problem. When i try to save a picture from a site (right mouse click and save as) to the hard disk of my pc, the response of firefox is slow. It takes about 6 to 10 seconds. I thought it was a matter of file size but it proved that it was irrelevant, because it was happening to pictures from 10kb to 500kb. I did the following:
    - clear history
    - clear cache from firefox and the folder ''cache'' in my profile
    - delete the files downloads.sqlite and localstore.rdf
    - i changed the ''browser.download.manager.scanWhenDone'' and ''services.sync.prefs.sync.browser.download.manager.scanWhenDone'' to false
    - clear the downloads window
    - disable all add-ons
    After all these, the problem still remained
    Then i started firefox in safe mode (help --> Restart with Add-ons Disabled...). The problem still remained.
    Then i disabled Microsoft security essentials (real time protection) and windows firewall. I do not have any other anti-virus or firewall on my pc. Nothing happened.
    Then i created a new profile (reset firefox). Nothing happened. So, one last attempt was left to do. Reboot with safe mode. So i followed the following steps.
    i ran msconfig and disabled ''Microsoft Security Client'' from start up tab and ''Microsoft Antimalware Service'' from services tab. So i did a safe mode boot with network support and windows firewall, disabled. Guess what. Nothing happened.
    I noticed that when i was trying to save pictures, during the process, there was a significant hard disk activity (the led indicator of hard disk activity was lighting constantly) and firefox on the left upper corner, shown the message ''not responding'' for about 6 to 10 seconds. You understand that saving a picture of 19kb in 10 seconds is not normal.
    Is this problem has to do with the cache? The hard disk is an SSD (solid state drive). Do you think it would be better to redirect cache to memory? (i have 6GB total RAM). This problem was also happening to previous versions of firefox, but i think that with this version, the problem is more frequent. It is not happening with every picture, but it happens with more than 65% of the pictures.
    It also happens when loading a web page, but it might be a matter of a heavy web page that uses many resources of my system, during loading. The problem is the same. Constant hard disk activity and it takes time to load the web page. The problem with web page loading, is not as frequent as with saving pictures.
    I think it is a matter of cache management. What is your opinion?
    Thank you.

    The cause to my problem was the jump lists, that Windows 7 introduced. There are two kinds of jump lists, automatic and custom. Automatic jump lists were causing the slow down of firefox through window explorer. Finally it was a problem of windows explorer and not firefox. Windows 7 introduced many new features that cause slow system performance. Anyway the solution to the problem is to follow the steps:
    1. Open mycomputer and on the address bar paste the path: %AppData%\Microsoft\Windows\Recent\AutomaticDestinations
    2. Press ctrl + a
    3. press shift + delete and delete everything inside the folder
    I think that the respective jump list of windows explorer is the one that starts with 1b4dd67f29cb1962, in case you don't want to delete every jump list in the folder. If you use firefox, download a file and then go to the above mentioned path and view files by date. The most recent file should be the correspondent with firefox.

    Over the last few day the interent has been crashing with the following response - "plugin container for firefox has stopped working." Why and how can I fix this issue?

    Same problem here. Firefox keeps freezing, sometimes for 5 minutes, then either starts working again really slowly or I get the plug-in error crash. This last time I copied what windows said about the error. This is the info:

  • Firefox will not open until Windows Firewall has opened at startup. A slow process and slows Firefox in Starting. Can this be corrected?

    Since installing Firefox the start up time for the computer has greatly increased as Windows Firewall has to be started before Firefox can open. Very annoying and can this problem be corrected?

    Firefox does this for security purposes. I do not recommend attempting to "fix" this.
    To boost starting time, you can try a Firefox preloading software.

  • Firefox has become extremely slow in the recent times

    Firefox suddenly has become very slow. It takes too much time to load all websites and even the typed words and scrolling has a great delay in appearing. It becomes unresponsive very often. I tried reinstalling it and even reset it. Its becoming a pain to use this to surf the net. Please do help!!

    I also have found that Firefox has become a dog. I've followed one thread that disabled the plugin-container with no help. 20.0.1 can hang for over a minute and actually hog my entire CPU so I can't even start Chrome! I like my FF plug-ins, but the performance problems of FF 20 are becoming intolerable and no one seems to know what the heck! Chrome does not present the problems and I have been visiting and working at the same websites. If many folks are encountering this mess, I suspect that FF is done for. I have actually found that the Android FF is also tending to slow down my smartphone - stall it! I am a few days away from just removing FF from my computing life.

  • Firefox has suddenly gone wrong. I was successfully running both Firefox and Internet Explorer 8 on Windows 7. I auto-accept upgrades including the most recent Firefox upgrade and the suggested upgrade to Adobe Flash 10.1. But after this, Firefox stopped

    Firefox has suddenly gone wrong. I was successfully running both Firefox and Internet Explorer 8 on Windows 7. My laptop is new and has plenty of RAM and HDD. I auto-accept upgrades including the most recent Firefox upgrade and the suggested upgrade to Adobe Flash 10.1. But after this, Firefox stopped working and does not work when I re-load Firefox 3.6. Also IE8 now works very slowly and does not locate major websites like Microsoft without a 'can't find the website message' and having to pressing Return a second time. When I do get to the Mozilla website and click on the button to try to download Firefox 3.6.6, I get this message "Oops! Internet Explorer could not find mozilla3.snt.utwente.nl". Can you help with what has gone wrong? As it stands, I can't use Firefox at all. Note: because Firefox did not work after the upgrade, I've downloaded the IE8 version of the Adobe Flash 10.1. What I really want is to be able to use both Firefox and IE8. But is this possible if they use different versions of Adobe Flash?

    I have been having the same problem as the original poster. After upgrading to Ffx 3.6.6, the program asks you to upgrade to Flash Player Plugin 10.1. I download and installed 10.1 only to find videos weren't loading.
    In my case, the problem is the previous installation of Flash Player (9.0.47) was somehow messing things up. To fix this, because I already had Flash plugin 10.1 installed I had to uninstall 10.1 using the uninstaller from adobe and then manually remove any files related the old flash player plugin 9.0.47
    Here is a run-down of my process:
    0. To check if you have a previous installation of the Flash Plugin lurking around, in Firefox go to Tools -> Add-ons -> Plugins (tab). At this point you may seen both Flash plugins.
    1. Proceed to uninstall Flash Plugin 10.1. Adobe provides an uninstaller here: http://kb2.adobe.com/cps/141/tn_14157.html
    ( you have to make sure you have nothing running when you execute the installer).
    2. On my Mac (sorry I don't know what it is in Windows) I searched the hard drive for any files/folders with "Shockwave". I found a folder called "Shockwave 10". It wasn't removed by Adobe's uninstaller. For safety I deleted it and then emptied the trash.
    3. I then went to My HD -> Library -> Internet Plugins.
    Remove the file and folder named "Flash player.old"
    4. Restarted; ran the Adobe Flash Player 10.1 installer. Restarted again.
    5. Opened up ffx and double checked the plugins list (see step 1). Version 10.1 is installed and available. Went to problem sites to test it out and Success!
    Hope this helps.

  • Firefox has taken over my computer to the extent that I can't get out of firefox back to my regular homepage and moreover I can't even log out or shut down.

    When I try to log on as I have usually done I get a small window
    stating that an error has occurred and when I click on what should solve the problem a larger white window appears stating
    I should not close the window...although several times I have
    not close the window all I get is 2 blue spinning circles.
    I feel like Firefox has taken over my heretofore routine
    usage of my computer and I have lost control. HELP!!!!!

    That file could be set as a Launch Agent or Daemon in your ~/Library or /Library, You could try to look for it or Safeboot your computer and then empty the trash.

  • After updating Firefox it will no longer open and i get the message "firefox.exe has encountered a problem and needs to close" end of story.

    Firefox was working well. One day I logged on to use Firefox and was prompted to update my version which I did. After or during the update the following message was given on the screen "firefox has encountered a problem and needs to close". It closed and now every time I click on the firefox icon I get the same message from Microsoft. That is all the information I get. Each time I go to open Firefox I get the same message. There is an error message attached to the Microsoft dialog box, but I don't understand what it means.
    I have sent it to Microsoft but no reply.

    Make sure that you aren't running Firefox in some compatibility mode (e.g. [http://en.wikipedia.org/wiki/Rosetta_%28software%29 Rosetta]).

  • Firefox has been crashing when I try to close it and now won't open at all.

    For some time now, Firefox has been timing out when I tried to close it, making it necessary to "force quit." Now it won't open at all. Even more strangely, I'm not able to send a crash report to Apple (I get the message "submission failed").
    I've tried downloading the newest version, downloading plug-ins, and starting in "safe mode."
    Also strange, in my bookmarks section the little icons had disappeared lately.
