Firefox is hanging A LOT.

My firefox is hanging almost every couple of minutes. Usually when looking at videos or games, but it had hung on a site as well. I've tried going in safe mode, cleared history, check computer for bugs. This only started since I downloaded the "upgraded" firefox. Is there a way to download a later version maybe?

Weeks of TRASH = FIREFOX 3.66
All three of my computers have been totally worthless since I upgraded to FF3.66. Each are built/configured differently. Each has a different OS. Each has all the above problems. Crashes constantly, RAM & CPU usage on a Q9650 is always near 100%. After screwing around for days I finally came here and found out that I was among a very large and upset group of users. With the last few upgrade I've had minor problems with my selection of add-ons Firefox disabled them for a later fix. I found a new DL today, 3.67 so I installed it figuring the problem was addressed. After installation of 3.67 it still says it's 3.66??
I went to their site to find help from them and couldn't get anyplace until I came here and read about my problem. Thanks for giving me a clear head so I could find a good solution.
My solution was to remove all Mozilla/Firefox products and then install other browsing options. It felt funny because for the first time in years I had to use Microsoft Internet Explorer to find other options. My computer is problem free and fast as usual now.
I wonder how many other users have abandoned them due to this BS?? I for one will probably stick with my new choices now.
YES, Weeks of TRASH = FIREFOX 3.66

  • Firefox hangs a lot!!!

    My Firefox hangs a lot when I open heavy graphic website. sometime it happens with the normal website with minimal graphic as well. I am using 20.0.1. I am planning to upgrade it to latest version but my belief is that the latest version won't work well in XP.
    here is the list of installed addons:
    copyallurls
    copyurls
    feedly
    firebug
    informEnter
    rankchecker
    roboform
    searchstatus
    seo for firefox
    startaid
    viewmarks
    desabled addon
    mozbar
    seodocotr
    skype click to call
    I would agree that my browser usage is bit different than average user. Hence can you please suggest which older version should I use. or is there any way I can optimize firefox for optimum performance?
    FYR.. my system RAM is only 1 GB.

    Is there any way to keep those addons and make my firefox lighter by optimizing it?

  • Firefox 7 hangs a whole lot in the past several weeks. I can hardly get through typing an email without it freezing and making me have to kill the program and start over.

    I am using firefox 7, windows 7 pro, 64 bit machine.
    If I am typing an email I never know if I can finish because it often freezes and I cannot get the mouse to do anything. I have to hit "control-alt-delete" and stop firefox and sometimes the process and then start over. Also firefox is consuming a lot of cpu resources
    (over 110,000k and sometimes near 200,000k). Is that normal?

    We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.
    #Enter ''about:crashes'' in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
    #Copy the '''5''' most recent Report IDs that start with '''bp-''' and paste them into your response here.

  • OS 10.10.1 Hangs a LOT

    I have never had this problem until now. I came back from New Years and turned my iMac on (late 2012 model, running 10.10.1) only to be extremely frustrated with hangs and freezes at odd times, such as:
    1. clicking on the Apple logo in the upper left on Finder to get the menu (sometimes hangs for as long as 15 seconds or more before displaying the menu and this was after a fresh reboot with nothing else running)
    2. Browsing through a folder of pictures, it takes a very long time to load the thumbnails of the photos, and also takes a long time for preview to pop up when I hit spacebar
    3. Simple browsing through my Facebook News Feed via Firefox (latest version) experiences constant hangs as I scroll
    4. Clicking on different emails in succession in Thunderbird (latest version) was causing a lot of unpredictable hangs
    5. Going to System Preferences and trying to click through the different sections there.... hangs.
    I could not get ANY work done at all and was absolutely exasperated when I searched Google for "mac os 10.10.1 hangs" and found a forum post near the top of the search results. I did as Linc Davis suggested and powered off the iMac, unplugged the cord from my uninterruptible power supply, and let it sit there for a minute or so before plugging back in, and powering on. Resetting the SMC.
    This seemed to have solved SOME of the issues and the OS runs a lot better now, but I am still getting some weird issues and the occasional hang, although the hang is not lasting as long as it was previously. Whereas before, it was doing it all the time on almost every action I tried to perform, now it is doing is MUCH less but still doing it occasionally and certainly more than should be happening on such a fast computer with 16 GB ram on a fresh boot of the OS and no extra software running. This is absolutely ridiculous.
    I have no idea what to do now. I'm almost afraid every time I click something.

    Thank you. Here are the results from the software you recommended:
    Problem description:
    System is hanging a LOT on many ordinary tasks as a click around the OS and normal programs like Firefox and Thunderbird, as well as navigating Finder, etc.

  • My iphone 5s has been hanging a lot. I bought it 15 days ago only.

    I got my iphone on 19th December and since then my phone has been hanging a lot. There have been more than 4 times that the phone has frozen and restarted. My software is 7.0.4. I have deleted the apps that makes freezing to happen. It could be that they are not optimized for iOS7, but even then why would the touchscreen be unresponsive at times and a game like angry birds go hang and a game like Deer Hunter 2014 stop loading completely out of the blue moon. I have mailed the developer of Deer Hunter but I wont do that with any other app. I am using an iphone first time in my life and this is what I am getting in a welcome drink.

    Search these forums for hints on how to maximize your battery life. after trying the many suggestions on these forums you still feel your battery is draining too fast Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

  • Firefox 31 hangs on startup with no error messages

    Simply put, Firefox hangs right on startup. I see it loading the two generic tabs and then the wheel spins and then it says 'Not Responding' on the top of the window. I have to force close it each and every time, and I've also tried the following solutions in no particular order to alleviate the issue:
    1) Ran SuperAntiSpyware and Malwarebytes last night for any possible infections. Reported back with nothing.
    2) Booted my laptop up in Safe Mode (with networking) and still couldn't get it to operate.
    3) Performed several clean uninstalls and re-installations which also included clearing out the profiles altogether and then trying to open it again, nothing.
    4) Booted up Firefox by holding down the shift key and resetted it to its default settings and then tried firing it up again. Nothing.
    5) Attempted booting up FF in Safe Mode with the shift key, nothing.
    6) Created a new profile and tried booting FF, nothing.
    7) Read this article http://kb.mozillazine.org/Firefox_hangs#Hyper-Threading about Hyper-Threading and followed the instructions which got it to operate, but I can't access the toolbar or the option menus. When I click on options Firefox closes with no error messages. I have a feeling this isn't the issue at hand but I figure I'd try it and at least I can get it to fully load and not hang.
    8) Deleted all Firefox extensions and Plug-ins, nothing.
    9) Enabled Firefox through firewall and antivirus settings, nothing.
    10) Updated my BIOS firmware as suggested in #7, nothing.
    I've done almost 10 different things and I still can't figure out why Firefox keeps hanging on startup. I've looked into Youtube videos for tutorials and others posted about the Java crashing that was happening in an earlier version of FF. Since its not crashing, I'm unable to look into the crash logs and pinpoint a crash number or anything because it just freezes and when I click to close it I get a message saying: 'Close program' or 'Wait for it to respond.'
    I'm running a 64 bit Windows 7 on an HP Pavilion g6-1c44wm Notebook PC
    Microprocessor 2.10 GHz Intel Pentium Processor B950

    Hard Drive 500GB 5400RPM)
    I'm trying to be specific as possible! Please help! I'm at the end of my rope here!

    Try to completely uninstall firefox, that means to '''delete''' the [http://kb.mozillazine.org/Installation_directory#Windows Installation directory] located for your 64bit in C:\Program Files (x86)\Mozilla Firefox\ , also, '''delete''' the C:\Users\<username>\AppData\Local\Mozilla\Firefox and '''if exist''', '''delete''' the C:\Users\<username>\AppData\Local\VirtualStore\Program Files\Mozilla Firefox.
    then download and install again a new full installer from : https://www.mozilla.org/en-US/firefox/all/
    disable firewall and antivirus and antispyware for a little bit, and run firefox. any luck ?
    thank you

  • I downloaded an update to Firefox last night, and now Firefox just hangs and won't connect. It started out okay this morning, but now it won't work at all.

    Even with a brand new computer, Firefox frequently hangs and/or quits spontaneously. I downloaded the latest update last night, and it worked okay for about a half hour this morning, then quit.

    Do you have Internet Security Software turned on in your Internet Explorer?
    I turned mine off, as I have Norton AV. Go into Internet Explorer and check to see if you have that on and try turning that off...and then try to get back onto FF. You may have to restart your computer, I'm not sure, as I'm not a techie. I just know that the Internet Security Software clashed with my Norton AV.
    Good luck!!!
    Donna
    PS Go with the user's suggestion above me, sounds the right way to go...thank God for the techies, eh? :)

  • When uploading an image from my documents firefox 5 hangs for several seconds to a minute.

    This in on an XP SP3 system. The problem seemed to have started with 3.6 and has been a constant issue even with current versions. When I upload any file firefox just hangs for a short while then it's fine for the rest of the day only to come back the next day. I relocated "my documents" and it went away, then a few weeks ago I did a clean install and the problem seemed to be gone for good. Now the problem is back.
    I thought it might be a disk issue, but it checks out fine using check disk.

    The speed of image searching isn't a problem for me. The trouble is, the automatic zoom function is lightning fast and I find it disturbing to the point that it makes me feel very ill.
    I very much want a way of suppressing it.

  • Firefox 4 hangs a little on every action - typing, moving the window, selecting a menu item, selecting a tab, ...

    Since installing Firefox 4 RC2, and now Firefox 4, Firefox constantly hangs on every action. Just in typing this message, the program pauses for a second or two every few words. Opening a tab, selecting a menu item or even moving the Firefox window incurs a brief pause of a second or two. This makes the users experience terribly slow. I've tried turning off sync and starting Firefox with extensions disabled. Nothing seems to help. I upgraded from RC2 but then deleted and reinstalled Firefox.
    I'm having this problem on my MacBook Pro, which is pretty new (less than a year old) and otherwise very fast (i.e., i7 processor and 8Gb RAM). I have the newest version of OS X (10.6.7) and have updated all extensions.
    I've watched my system monitor and Firefox is constantly and repeatedly going from low to near 100% CPU use every few seconds. I have no special, unusual settings (I've gone through preferences).
    This is getting so bad that I'm about ready to abandon FireFox. Any suggestions would be helpful.

    I had the same problem, I kept searching and found this:

  • Sites using flash/shockwave cause Firefox to hang.

    If the shockwave flash plugin is enabled on version >22, visiting a site that contains flash content will cause Firefox to hang/react extremely slowly. I've tried disabling all add-ons with no effect.
    I'm using shockwave flash 11.2.r202.310 but it doesn't seem to matter when version of flash I use.

    Thanks for the replies guys.
    ComputerWhiz: No firewall or AV installed on my laptop.
    cor-el: Nothing works. It is the shockwave flash plugin + >=v23 that is the problem. I've tried safemode, I've completely deleted everything eg moving the .mozilla directory and started a virgin firefox with the same results.

  • Firefox 4 hangs at loading so I can't see the toolbar to fix it. I just downloaded it.

    Firefox 4 hangs BEFORE getting the toolbar and I can't get in to change settings such as system restore settings and the other solutions you have in the help section. ALSO, your help section only shows 3.6 and earlier solutions which really bugs me. If you're going to come out with new version PLEASE put out the solutions for it.

    Sorry, but I don't. Have never used a TV as a monitor. My suggestion was just a thought. Perhaps someone else will have a workable solution.
    If the menubar is visible then it may be some adjustment that's needed perhaps on the TV itself which has it's own zoom. If it's set to an incorrect screen mode then it may cut off portions of the display - just a guess. Try switching the display mode on the TV to see if that resolves the problem.
    As for the mini itself I'd set it to a resolution mode that most closely corresponds to what the TV can display. If it can display 1080p, then set the mini's display resolution to 1680 x 1050.

    == This happened ==
    Every time Firefox opened

    Hello.
    You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.
