Why cant I even start Firefox?

This problem happened when I updated Firefox. The server crashed and could not even be opened to the startup page.
The mozilla Crash reporter is always shown.
I have deleted the software and re-downloading firefox several times but failed.
The same crash reporter is shown everytime I reinstall firefox.
It is impossible to open firefox at all!

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

  • Hi, i updated to firefox 8. i cant even get firefox to start. it states a previous update needs to take effect and a reboot is needed. but nothing happens.

    i updated to firefox 8. i now cant get firefox to operate at all.
    it asks to reboot pc everytime i try to start or uninstall.
    nothing happens after reboot as you try to start firefox again and it askes the same thing

    See the [[Latest Firefox issues]] article. Try the first suggestion, to download the Firefox installer from mozilla.org/firefox and then reinstall Firefox (see [[Installing Firefox on Windows]] for detailed instructions).

  • Every time I start Firefox in an unpriveleged login I get an error box saying that an update installation has failed, even when it's up to date.

    Firefox 19.0.2; on Windows XP Pro Service Pack 3 build 2600.xpxp_sp3_gdr_130105-0416.
    I normally work using minimal privileges - so the user from which I mostly run Firefox doesn't have sufficient privilege to install a Firefox update. Now and again I log in as a privileged user, start firefox, and grab the latest version. However it happens quite frequently that Firefox goes into a mode where on Firefox startup I get an error window saying that it failed to install the update. When that window is dismissed, Firefox starts up and of course it's the latest version. Nothing I have tried appears to have any effect on this, but always after some period of time - in which I will have logged in and out a few times and probably started and stopped Firefox dozens of times - for no reason that I can discern it stops producing this error message and begins to start up without the error. This lasts a few days, and then it reverts to getting the error message.
    In case it's useful to anyone, the error window is labelled
    Dh'fhàillig ùrachadh a' bhathar-bhuig
    which translates roughly to "The software's update failed"
    and the text in the window is
    Cha do ghabh an t-ùrachadh a stàladh. Dèan cinnteach nach eil lethbhreac eile de Firefox a' dol air a' choimpiutair agad is ath-thòisich Firefox an uairsin is feuch ris a-rithist.
    which is roughly "The update couldn't be installed. Make certain no other copy of Firefox is running on your computer and then restart Firefox and try again".
    I have of course done what the window tells me; it has no effect (if it had that would mean the OS security was broken) which is a good thing but suggests that the message in the window is a bad thing. I also tried updateing from the Firefox help menu (and was relieved to see that didn't work). Using a priileged user to install the update gives the unprivileged user the latest version, but doesn't ,ake the startup message go away.
    I have a suspicion that what is happening is that Firefox running in unprivileged mode finds a security update, downloads it, and fails to install it, instead of recognising that it's running in unprivileged mode and just warning the user than an update is available; once it has done that the update remains downloaded in the unprivileged user's space, and even when the update is installed by the privileged user so that all users now have the updated version Firefox tries to install it despite its being already installed whenever the unprivileged user starts it up. If so, that would be a rather unpleasant problem, since it would tend to encourage people always to login with sysadmin privileges.

    hello, when this is happening after you've already updated firefox with your admin account, try to delete the ''updates'' folder and ''active-update.xml & updates.xml'' within the %localappdata% folder of your restricted account like it is described in http://kb.mozillazine.org/Software_Update#Software_Update_not_working_properly

  • Why does my computer create web connections to addresses in the Amazon, Google and Youtube range when I start Firefox?

    I think I already disabled all the updating functions, yet, SOMETIMES when I start Firefox, (with about:blank), my network monitor shows one to five connections to IP addresses mostly in the 74.125.225.x, 74.125.227.x, 74.125.228.x, and 72.21.x.x ranges. Those ranges include Google, Amazon, and Youtube.
    I use Kaspersky, and have scanned multiple times for malware, and even had their technical support look into my computer. They see no malware. It is the Kaspersky Network Monitor that revealed the problem.
    As I find them happening, I try to jot down the addresses, (quickly, because some of these connections only last a second or two), then add those to a firewall rule I created to try to combat the problem. Yet, next time I start, new addresses are "attacking". Of course, some get away, because I don't get the address jotted down before it goes away. At one point I used masking that ended up keeping me from Google and Youtube, so I have to add the addresses individually, and my block list in that one rule is 13 items long now. The only IPs not in those ranges are 23.5.251.27, and 173.194.46.5. Not sure where those go.
    I used to get attacked by addresses in the range that includes Amazon ... 72.21.x.x. I have a separate firewall rule for them that has 33 addresses being blocked.
    I should not have to do all that. Firefox should start and just sit there quietly until I start clicking or typing in it. This has been happening in Firefox versions going back to 11. May have gone on before that, but I wasn't tracking it then.
    Also, it doesn't always happen, or, more precisely, with addresses I have not already blocked, (because my only way to know it's happening is when the connections are allowed to be made). It does not always happen right after Firefox is up, but sometimes several minutes later. I have started Firefox and just sat and watched the network monitor without doing anything in Firefox, and have seen this happen up to 15 minutes after I start Firefox ... mostly just two or three minutes when there's a delay at all.

    Firefox does not do anything but sit on about:blank after I start it as long as I have a firewall rule enabled that completely blocks these subnets:
    74.125.222.0/24
    74.125.227.0/24
    74.125.228.0/24
    173.194.46.0/24
    173.194.115.0/24
    173.194.121.0/24
    64.233.171.0/24
    54.230.90.0/24
    54.230.88.0/24
    72.21.194.0/24
    72.21.195.0/24
    72.21.215.0/24
    207.171.163.0/24
    Otherwise, Fire fox creates connections to one to five addresses in those ranges. Note that there are more than 5 subnets above, but usually three connections satisfies whatever purpose these connections are being made for. If I had some links or whatever that is causing these connections, I would expect all of them would come up every time.
    Also, these connections do not start immediately upon starting Firefox, they wait up to 15 minutes to start ... fifteen minutes of just sitting idle ... no actions on my part that could possibly initiate them. Usually these start within three minutes. A typical ploy of malware is to wait until no one is looking, or the until there's a forest to put their tree in so it won't be noticed.
    While the above rules are in place, I do not have access to Amazon, Youtube, or Google, (or any of the various blog sites and services sponsored by Google, including Google Maps and Gmail). That list may not be complete, as I have other firewall rules in place that mainly block individual addresses.
    It seems to me as simple as; figure out who owns those subnets, and you have your bad guys. Then go after them.
    It's true that I have a bookmarks to Google, Gmail, and Youtube, but these are not "active" bookmarks nor RSS feeds. I have not voluntarily gone to Amazon on this computer.
    The traffic being transmitted is unknown. It is usually not extremely large amounts of data ... less than a meg, but I have seen close to a Gig transmitted out of my computer, and over 400 meg transmitted to my computer, when I was not paying attention to block the offender. Even if it's small amounts, things like cookies, path structures, configuration settings, histories, etc. do not involve a lot of data, but, to me, represent a security breach, if someone decides to look at them unsolicited by me, not unlike your landlord, mortgage holder, or neighborhood police officer walking into your home while you're not there, and taking pictures of, or simply inventorying your belongings.
    It is VERY much like some sort of backdoor malware. No malware is detected on my computer.
    I looked at the suggestion above for OS changes for logging HTTP activity, but the author neglected to include instructions for backing out these changes after using them. If this were to create more jewels in a drawer the thief has access to, reformatting and restoring my drive is not the kind of back out process I enjoy. Therefore it would be foolish to apply them. To me it would be like bungee diving with no bungee. Fun until you hit the bottom. Give me the bungee, let me make sure it's short enough, then I'll dive.

    remember how/if we resolved it.
    If this is an impotant issue to you, I suggest that you open a case with

    This is a rather important issue, I have seen another post with a similar problem.
    While not being a show-stopper it certainly raises concerns.
    The application works ok until the application exits (in both development and
    executable form)
    Apparently this did not happen with Tux 7.1
    It does with 8, I do not have 7.1 so I have no workaround.

  • How do I start Firefox 4 from KMenu when I downloaded and installed Firefox4.0.tar.bz2 (only launches from terminal), and 'apt-get' installs Firefox 3.6.15 even though I tried to "--purge" it from Linux?

    I downloaded and installed Firefox 4 RC using tar.bz2 so that I could still use Firefox 3.6.15 as per normal, having to start Firefox 4 using the terminal which worked great (except for many videos on different websites). When Firefox 4 was released, I suppose I was in a hurry to get it to work normal from my menu, but it kept saying that 3.6.15 was the latest version (I'll be quite embarrassed if it wasn't available for Linux users - I do love Firefox!). I did something silly, like purge Firefox from my operating system (Kubuntu 10.10) and when I reinstalled it was still 3.6.15 (it wasn't really downloading, but unpacking). Am I in too much of a hurry or is there a fix-it? I can use Firefox 4, but only through the terminal and I suspect it is slower than it should be. I would like only one version now.

    First, that cannot be an iBook G4 as that machine cannot run Snow Leopard let alone Mountain Lion.  To run Snow Leopard it has to be an Intel processor, not a G4.  What does it show as the Model Identifier in About This Mac, More Info, System Report, Hardware, Model Identifier?
    Second, if you have erased the hard drive there should not be remnants of any prior content.  Even though Disk Warrior is saying nothing is wrong with the hard drive, it sounds as though there are problems.  You may want to consider simply replacing the hard drive so there are no questions about faults.  A good source is OWC, http://www.macsales.com where they also have on-line videos showing how to do the replacement.
    Third, you could also try again to restart using the Snow Leopard DVD/CD and use Disk Utility on that install disk to erase again, and do it a couple times, then try to install.  If it continues to refuse, then it sounds as though there is a fault with the hard drive.

  • I copied this from your 5.0 download information: "All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again." When I opened my computer today all my apptabs from yesterday had disappeared. Why?

    Your download page for 5.0 stated: All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again.
    I liked the convenience of using App Tabs and was disappointed to find that the ones I had set up yesterday were gone today. Am I doing something wrong?

    Works fine for me, I can simulate your problem by improperly closing Firefox.
    The correct way would be to close the windows you don't want and then to exit Firefox through the File ("'''Alt+F'''") menu then use '''Exit''' or '''Qui'''t depending on your system.
    But '''I can simulate your problem''' by closing the good window with "X" in the upper right-corner first (the one with the app-tabs) and then close the other window by any means.
    You restart Firefox and open a window, since you closed without app-tabs there are none so you just see a window with your home page.
    Firefox has some things added to Firefox 4 and therefore in Firefox 5.
    # "'''Alt+S'''" (Hi'''s'''tory menu)
    # "'''Restore Previous Session'''" (that's the window without the app-tabs, but you have to this first)
    # "'''Restore Recently Closed Windows'''" -- can choose which window to reopen based on name and the mouse-over tells how many tabs. or you just use "'''Restore All Windows'''" without the guessing.
    ''I know you are on a Mac, and this affects Windows user more than anybody else, but it does affect other systems besides Windows, occasionally, perhaps more often now with the plugins container.''
    The following may not completely eliminate having to terminate Firefox through the Windows Control Panel but it will come very close.
    '''Plug-in and tasks started by Firefox may continue after attempting
    to close Firefox''' The "X" in the upper right-hand corner closes the
    Window (same as Ctrl+Shift+W) but even if it is the last Firefox window,
    it does not necessarily close Firefox .
    The only '''proper way to exit Firefox''' is to use '''Exit''' through the
    File menu, not the "X" in the upper right corner of last Firefox window.
    In the Firefox 4 and 5 that would be Alt+F then X
    * '''Firefox hangs''' | Troubleshooting | Firefox Support <br>http://support.mozilla.com/en-US/kb/Firefox%20hangs#w_hang-at-exit
    Use the '''Windows Task Manger''' to remove all running firefox.exe in the "'''Processes'''" tab of the Windows Task Manager, then restart Firefox.
    If Firefox will still not start, remove the parent.lock file from the profile which is created each time Firefox is started to prevent other Firefox tasks from running, see<br>
    http://kb.mozillazine.org/Profile_in_use#Remove_the_profile_lock_file
    '''Avoiding Problems with close/restart''' ''choose either extension''
    :Use to close and restart Firefox after enabling or disabling an extension, switching to a new theme, or modifying configuration files, then you don't have to worry about delay or have to look in the Task Manager to see if Firefox is closed yet.
    Both extensions use the same keyboard shortcut "'''Ctrl+Alt+R'''" or a file menu option.
    *"'''Restartless Restart'''" extension for Firefox 4.0+ only (2 KB download ) <br>https://addons.mozilla.org/firefox/addon/249342/

  • I have to re-install adobe flash for firefox every time i start my computer even if firefox shows that my adobe flash is working it does not.I also get notices from the websites i visit (get flash e.t.c.)

    i have the latest firefox 10.02 in win7 and even if firefox shows is installed my adobe flash is not working so i have to run the flash installer every time i start my pc.After this everything works fine until the next start when i have to run the flashinstaller again

    There are two versions of the Flash Player plugin. One is ActiveX and only works in IE. It sounds like you have that one installed. The other one works in all other browsers.
    What seems to be happening is that you have security software that's blocking one of those versions of Flash/restoring your computer state and so it gets uninstalled when you start your computer. The other possibility is that there are permission issues. Unfortunately, this isn't something that Firefox can control; it's a problem with the Flash installation (Firefox is dumb and just looks in the registry for a list of installed plugins to load).
    Make sure that you're an admin on your computer when you try to install Flash and that you check your security settings. If that doesn't work, try posting to the [http://forums.adobe.com/community/flashplayer Adobe community forums] to see if other people have had similar issues and know how to address them.

  • Upgraded libx*** and now i cant start firefox [Solved]

    Well i did a pacman -Syu , noticed lots of x libs upgrading and then rebooted , now i cant start firefox , this is the terminal output
    The program 'firefox-bin' received an X Window System error.
    This probably reflects a bug in the program.
    The error was 'BadRequest (invalid request code or no such operation)'.
    (Details: serial 1033 error_code 1 request_code 154 minor_code 2)
    (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the --sync command line
    option to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error() function.)
    Any ideas how to fix this ??

    Hi Jeff,
    I am not certain what "the HTML5 player" is.
    To repeat my earlier question:
       "Why doesn't Adobe address this? Searches reveal that there is a plethora of people having the same problem."  See this link (https://www.google.com/search?q=adobetvdoesntworkonfirefoxsite:forums.adobe.com&lr=&hl=en&as_qdr=all&biw=1920&bih=748)
    I could search help pages all day long if I didn't have to, y'know... work. This is obviously a problem to which Adobe needs to research the solution.
    I am within the requirements of the service stated on the AdobeTV page, yet it doesn't work. Is it too much to ask that Adobe throw me a bone here?
    Sorry if I sound frustrated, but I spent hours of my time a couple of months ago, the last time I wanted to use AdobeTV, trying to figure this crap out and finally just gave up.
