Firefox has randomly stopped working.... i have uninstalled and reinstalled and click on icon at bottom of desktop and circle starts then stops and nothing.

I used firefox when I turned my computer on. Played a few games on facebook and got off firefox..... forgot do check my email 10 mins later and firefox wouldn't work. It has done this many time before but I just would restart my computer and it would start working.... I did just that and when I click the icon at the bottom of my desktop the firefox emblem lights up and the blue circle starts to turn for about 5 seconds and then the circle disappears and the emblem fades and nothing ever happens... I uninstalled it and went to the webpage and downloaded the newest one and reinstalled it and still the same problem... not sure what is happening and im sure i lost all my cookies and bookmarks but i just want firefox to start working again...........................................

  • Firefox 4 would not work. I uninstalled and reinstalled. Wouldn't work. Uninstalled and went back to 3.6. Won't work or uninstall. Says its running but it isn't. Cannot unistall or make it work. What do I do?

    After I upgraded to Firefox 4 nothing worked very well. It was slow, crashed a lot and froze, so I uninstalled and downloaded and installed again but then it wouldn't work at all. So uninstalled again. I decided to try 3.6 again as it worked well before , but now it won't work. I can't uninstall because it says Firefox is running and to close it but I have nothing open so how do I close something that isn't open? Never had trouble with Firefox but I'm about done with it. Please advise as to how to fix this. Firefox was in safe mode then it wasn't. What a mess.

    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 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.

    * Use Restore or Maximize in the right-click context menu of the Taskbar icon to set focus to the Firefox application if you do not see the Firefox window.
    * Open the system menu of that Firefox window via Alt+Space and see if you can move and resize that window.
    If that works then close Firefox (File > Exit/Quit) to save that setting.

  • Can someone help me when Firefox closes randomly it removes all the cookies and cache, and I am not able to restore lost tabs...?

    For a while now Firefox has randomly shut down for reasons unknown. Sometimes windows reports the error but not always. When I start Firefox back up again, it does not restore my tabs. Also as an added bonus it deletes the cookies and cache, and I don't know why. Furthermore this occurrence has become more and more frequent. Just in the last hour along before writing this complaint, Firefox crashed three times right as I switch users, but not every time I switched. I am a taboholic, addicted to tabs, sometimes 70+, and this is the final straw. This frequency became more and more prominent a few days ago. When it first crashed, Windows was kind enough to let me know of the error which first occurred one to two weeks ago. It has become the very bane of my internet surfing. Someone please help, or I will have to renounce my allegiance to Firefox and switch to the dark side that is Crome.

    <blockquote>... or I will have to renounce my allegiance to Firefox ...</blockquote>
    There is no citizenship oath involved in using Firefox, it's a piece of software.
    Look, if Firefox isn't generating any crash reports, you more than likely have an operating system or hardware issue. If Firefox is generating crash reports you can retrieve that information and post the report numbers here.

  • I have uninstalled and reinstalled the most current edition of Adobe Reader, including the patch. When I open a PDF file, the screen is first grey, then viewable, but the message "Adobe Reader has stopped working" comes up. How do I remedy this?

    RR,
    One thing often tried first is to create a new document and File>Place the corrupted one to see how much may be rescued that way (remember to tick Paste remembers Layers in the Layer palette flyout/dropdown first, and to untick it afterwards).
    Here is a website where you can see whether it can rescue the file, and if it can, you may pay for a subscription to have it done,
    http://www.recoverytoolbox.com/buy_illustrator.html
    and another similar website,
    http://markzware.com/adobe-software/fix-illustrator-file-unknown-error-occurred-pdf2dtp-fi le-recovery/
    As far as I remember, the former is for Win and the latter for Mac.
    Here are a few pages about struggling with it yourself:

    Failing a full recovery, hopefully you have one or more earlier versions and/or bits of artwork saved before it happened.

  • FireFox auto updated to 6.0 this weekend and has not worked properly since. I have uninstalled and reinstalled. Made sure all windows componets were up to date and still no joy. Any idea? Windows 7, 64 bit, normal configfuration. It is extreamly slow.

    FireFox auto updated to 6.0 this weekend and has not worked properly since. I have uninstalled and reinstalled. Made sure all windows componets were up to date and still no joy. Any idea? Windows 7, 64 bit, normal configfuration. It is extreamly slow and never finishes loading ANY page.

    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.

  • I can't open tabs on my MacBook Pro. I have uninstalled and re-installed Firefox several times, but it will still not allow me to open other tabs after it has gone to my homepage.

    I cannot open any tabs on Firefox. It opens to my homepage, but there is no line for a URL address. Therefore, there is no way to type in a new URL address. I have uninstalled and reinstalled Firefox twice and it has not helped. I am a former PC user and just switched to Mac.

    Try restore as new using computer iTunes.

    Why are you posting in this forum about what occured with an independent service provider?  How is is at all relevant to Apple??  In fact, service by any person or business not authorized by Apple voids any waranty.
