Non Responsive Firefox Hangs

First thing is when I start firefox I get a script error message that has to do with the nsSession Store. I get this three times in a row.
Also Firefox keeps becoming non responsive. I type a couple of words, wait, type a couple of more, wait, and so forth. This happens with everything, scrolling, clicking on a tab, clicking the back button, clicking on a link. I'm fed up. I thought the new update to 8.0 would solve it but it didn't.
Help!!!!

I solved the problem. I closed all my saved tabs and started over with saving them. Problem solved.

  • Firefox 13 is unusable hanging/non-responsive. I've downgraded flash, uninstalled plugins & un/reinstalled Firefox but I can't use it to try other possibl fixes

    Since updating to Firefox 13 it not only runs slow but hangs and becomes non-responsive on all different websites. I was told that the most recent Flash update was known to be incompatible with Ffx 13, so down-dated Flash and uninstalled non-essential plugins - which definitely helped, but has not fixed the problem.
    I haven't even been able to try the other potential fixes I've found on the Support site (adding into my computer's safe settings in case of firewall issue or creating a new profile) because Firefox won't work long enough for me to access them. At this point, shouldn't I just down-date to the last version of Firefox??

    All of a sudden firefox has become unstable - its hanging on the NYTIMEs website. I've done done everything - uninstalled, reinstalled, removed all add-ons, used default themes, reset firefox. Some serious problem here - I had to switch back to IE9. (Version 16.0.1 Firefox running under Windows 7)
    Oh by the way, I'm having the same problem on different computers all of which are running the latest firefox under Windows 7

  • Firefox will not open. Hangs at "connecting" stage. Non-responsive even to process shut-down via task manager.

    Starting yesterday, Firefox will not open at all. It hangs at the "connecting stage." For hours. It will not shut down even using the task manager for applications or processes, and it locks up virtually every other application. I thought I managed to save an open Word document yesterday - it looked like a slow, but normal save during the Firefox hang, but the document was empty when I restarted my computer.
    Even though my machine is not pentium 4 based, I tried starting using the Windows XP/M configuration, I downloaded and re-installed (over the top of) the existing version, I verified that no Mozilla processes were running before trying to start Mozilla, and tried creating a new profile. Absolutely no success. Every time (of the dozens) I have tried to start Firefox I have had to force a hard shut-down to get out of the application. I have now unpinned Firefox from my task bar because I keep forgetting and hitting it by reflex.
    I am running version 11.0 (at least that is what I just downloaded - I am not positive what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3, 2.4 gHz, 4 GB RAM, 64 bit OS.
    Next option is to restore to a previous version. If that doesn't work, I will uninstall and start over from scratch.

    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • Now that I was sent by Microsoft to your download update site to get the latest version 4.0.1, Firefox crashes (becomes non-responsive) before opening any site page I try. When will you fix this problem?

    For two weeks I have tried to use your automatic download of the latest version 4.0.1. It would sit there telling me it is trying to connect to the download computer for hours, several times overnight. Then, it became non-responsive and error messages were sent to Microsoft who directed me to your download site. After downloading your latest version several times, the new page would open. After selecting a bookmarked site, it would open (sometimes only partially) but when I tried to scroll down, it would freeze up and become non-responsive, again prompting error messages to Microsoft. They must be getting a kick out of this. I'm running a Gateway 7200S desktop with Microsoft XP and Intel single range Pentium 4 processor. I have been using your Mozilla Firefox as my default browser for several years with much satisfaction. Unfortunately, whatever upgrades were made have rendered it useless for me.

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

  • In Yahoo email, I continually get "non-responsive script" and my system hangs so I can't do anything. Doesn't happen in IE.

    This is an intermittent problem that seems to become worse as I continue a session in Yahoo email. I suddenly can't scroll, continue typing an email, or even switch to another site. A message window pops up that says a non-responsive script is running in the background and lists one of at least two different Yahoo mail client addresses at the bottom of the message. Sometimes responding to the message results in nothing but subsequent messages saying the same thing. The only thing I can do is close Firefox and open IE to continue with my emails. I don't remember the specific URLs.

    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:
    * [[Troubleshooting extensions and themes]]
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

    Oops - for some reason, this problem now seems to have gone away. May have had something to do with Flash. I'll keep my fingers crossed.

  • TS3430 iTunes hangs and is non-responsive

    Hi all,
    If I start iTunes in safe-mode on my Windows 7 Pro 64-bit system I have no problems.

  • Why does iCloud email run so slowly in Firefox? Typing is frequently stopped and "non-responsive" shows up and everything freezes for a while

    Why does iCloud email run so slowly in Firefox? Typing is frequently stopped and "non-responsive" shows up and everything freezes for a while. Doesn't happen with Outlook or Google?

    Hi,
    You can consider the [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems Reset Firefox] feature via '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information'''. If it is okay, you can then install the Mozilla Archive Format add-on.
    If you have security software installed you can try to delete all existing entries for Firefox and its sub processes in the different configuration modules and try to fully trust/allow Firefox afresh. Even after network access is completed, Firefox would still need unlimited access to its disk cache/memory as well as its files. Please see [https://support.mozilla.org/en-US/kb/Firewalls this].

  • I restored Firefox to its default settings but the slowness, crashing and non-responsiveness are not resolved

    Hello fellow-users of Firefox,
    I followed the advice stated in the Support article about slowness, crashing, etc. by restoring Firefox to its default settings. But the problems didn't go away. The browser remains slow and still gives me error messages about a non-responsive script or plugin and crashes. To make matters worse I don't see the menu items on the top toolbar I was so used to using, like File, Edit, View, etc. I used the View menu very often to zoom in on texts too small for me to read. Now I can't do that. I tried to drag some icons from the menu on the top right-hand corner of the page onto the top tool bar above the address bar, but this is not the same as what I was used to using before, And there are no File, Edit, View, Tools icons in the menu. So now I'm seeing my g-mail inbox in tiny little characters. I tried using the magnifier suggested in the Troubleshooting page of Support, but it's too cumbersome so I gave up.
    Would someone kindly please help me out on these issues? Thank you very much in advance.
    Regards,
    Tom Graciano (globmart)

    My pleasure!! :)

  • Firefox hangs, links don't click through, delayed response on some links

    Firefox hangs, links don't click through, looong delays on some links

    i have been using firefox for many years but now Im getting fed up with pages hanging.. it happens when the page is flash enabled.
    i tried ie and chrome and both work properly - I just dont like them.. please fix this!
    running win7 on a HP 4310s laptop brand new with all updates installed... my extensions are flashgot, xmarks, image toolbar, java, office, acrobat reader.
    I tried safe-mode and it still hangs!
    I also noticed that when I have two tabs open or more and I try to close firefox from task manager it will un-hang but only for a while - I cancel the closing and continue using the browser as normal... if during this time I navigate away from the flash enabled page then it continues normally. If I stay on the flash enabled page or open a new one it hangs again shortly after.

  • Firefox 6.02 became non responsive in my XP SP3. Once started, never respond to second click and dragging. Can't be closed in Task manager process. Still there after reboot. Only can be stop by shutting PC down and wait a few minutes. !How to fix it?

    At the same time; both Chrome; IE8 and Opera remain working. Whenever it became non responsive, there is no way to stop the process unless I turn the PC off completely(and it drag this process too). I reinstalled a few times but problem remains. It even drag the PC reboot .

  • IPhone hangs and non responsive

    Hi,
    I need someone to help me figure out what could be the problem with my iPhone which i got on Jan 9th 2009. I understand it still under warranty but i would like to know if iPhone itself is non responsive or its only my phone which doesnt respond sometimes and screen flashes sometimes.
    Thanks

    Page 34 of the manual:
    "If something is not working right, restarting or resetting iPhone will likely solve the
    problem.
    Restart iPhone: Press and hold the Sleep/Wake button until the red slider appears.
    Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and
    hold the Sleep/Wake until the Apple logo appears.
    Reset iPhone: Press and hold the Sleep/Wake button and the Home button at the

  • Firefox hangs (at anytime; nothing works/helps; keyboard useless) & constantly get no response/action; I get Firefox "not responding" message at top-left of window.

    Firefox hangs at anytime. Nothing works, (mouse/keyboard). Sometimes after 1 or 2 min. it works again, other times it freezes & I must re-boot (cut power & restore power) as keyboard or mouse does not respond. This happens at anytime, not when doing any specific task. Also have an unrelated question: I have have 2 Firefox icons on my desktop & 2 on my bottom toolbar, one reads as "Mozilla Firefox" & one as "Mozilla Firefox (2)". Is it possible I have 2 versions/programs installed & if so, how do I verify & correct this?

    You may somehow have installed a second copy of firefox. (I deliberately have multiple versions installed) Have you been trying the Beta or Aurora channels of Firefox ?
    You may have just copies the shortcut icons. I use XP but assume Vista is similar, and that if you right click the icons they will allow you to see the properties, that will include the path to the firefox program ''firefox.exe'' . Do both shortcuts point to the same file and location ?
    Another possibility is that one icon is for normal use, and another for safe mode, again something you will discover if you study the properties.
    For general information see

    *[[firefox is already running but is not responding]]
    There are currently two reasons for hangs that are frequently reported

  • Non-responsive scripts after installing Flash Player 11.3.300.257

    Adding more info, I do not happen to have RealPlayer installed.
    After updating FlashPlayer to the latest version I experienced non-responsive scripts - I use NoScript plugin with Firefox, as well as Java 7 update 4.

    Java 7 update 5 has been just released, thanks for replying.
    I did not install it though, in order to try to reproduce the problem.
    I am a Mechatronics Engineer and I have a non-common OS and software configuration.
    There is a numerical simulation application in my system which requires a programming language compiler to run, and such compiler requires the OS primary SDK and framework to be "understood" by the system.
    That said, I believe all the debugging routines might be somehow limiting FlashPlayer abstraction layer functionalities.
    As awkward as it may seem now, Firefox did not crash after one absolutely random measure I took.
    I opened this page: http://www.adobe.com/support/flashplayer/downloads.html and downloaded Windows Flash Player 11.3 Plugin content debugger (for Netscape-compatible browsers) from this link: http://download.macromedia.com/pub/flashplayer/updaters/11/flashplayer_11_plugin_debug.exe.
    Although there is a hanging before opening the about page and Youtube, flash content is indeed presented.
    Well, there might be a different abstraction layer approach regarding this content debugger version.
    I wait for further insight from you guys.
