Firefox will not start at all

New versions of Firefox will not start and only bring up the crash reporter. I've tried starting in safe mode, I've deleted/created new Profiles and I've uninstalled/installed Firefox over and over. I can still download 28.0 and it has no problem opening. Below is the latest Crash ID from 35.0
Crash ID: bp-4ac8fb2d-9a2a-4a6a-a9e4-06cc42150125

hello sid.robinson, this crash is caused by the "Digital Guardian" software by Verdasys that is running on your computer. Please see if there's an update available for that program.

  • Firefox will not start at all ... not even profile mananger will start

    After an auto overnight reboot initiated by a Windows update (XP 5.1 SP3) Firefox will not start at all ... not even Profile Manager ... all that happens is a few seconds of hourglass on the cursor and then nothing ... this is happening on two different computers at the same time ... identical symptoms ... any advice?
    == After overnight reboot by auto Windows update

    I had the problem after I restarted the computer when Firefox indicated that was needed to install updates. After that every attempt to start Firefox resulted in no response at all. I went to my program list and found Firefox Safe Mode. That started OK. I then closed it. After that Firefox started OK.

    Have you tried to start Firefox in [[Safe Mode]]?
    What about [[Managing profiles]]?
    Try to download the latest Firefox (3.6.4) from website. I hope your settings will not be lost; possibly, it was something with network connection, and Firefox updated only one half of itself; that's why I recommend to download it from website and install manually.

  • I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

    I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
    The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

    Did you check your security software (firewall)?
    A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, 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.

    Just installed Firefox 3.6. Firefox will not start and Firefox safemode does not start either. Using Task manager I do not see if started either. If I create a new profile and start from that window, Firefox starts up. I see no error windows/messages. I do have it listed in my Firewall as an exception program with Permit All.

    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

  • After removing system fonts and reinstalling fonts, FireFox will not start

    After removing system fonts and reinstalling fonts, FireFox will not start! When I start FireFox the "Mozilla Crash Reporter" opens as if FF just crashed??? I don't see any records in event viewer. I am using FF v3.6.3 on a Windows 7 box. I tried uninstalling 3.6.3 and installing 3.0.18 and had the same problem!

    The files with submitted crash report ids are inside the ''submitted '' directory, from the directory you found the LastCrash.txt timestamp file.
    The file names will begin with '''bp-'''
    There might be more information from the crash report, but it might just tell us you are crashing the first time Firefox tries to use a font.
    One thing I suppose you could do is select only those fonts you've got in Tools -> Options -> Content -> Fonts and Colors -> Advanced and then uncheck the '''Allow pages to use their own fonts''' option.
    See http://support.mozilla.com/en-US/kb/Options+window+-+Content+panel#Fonts_Dialog
    To be honest, I can't find anything on this Netscape Font Navigator and it sounds highly dubious.

  • Firefox will not start, after reboot.

    For a few months now Firefox will not start after I reboot my computer. In order to get it to start I click the exe then must go into task manager kill it, click the exe again, kill it again then, from there it will typically start, but sometimes it may take one or two more trys. When clicking the exe firefox will appear in the task manager under processes but will will start with ~7% CPU usage, then quickly drop to zero every time until it does actually open and start. I have ran a full system recovery and started anew after reinstalling mozilla several times failed to fix the problem. I run virus and spyware checks often and come up clean, and also run Chrome as a default browser.
    == This happened ==
    A few times a week

    Hello Tom.
    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.

    Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

  • After upgrading to 27, firefox will not start. Saw an error message during the upgrade process.

    After upgrading to 27, firefox will not start. Saw an error message during the upgrade process but cannot remember.
    Tried to run firefox.exe -P but receive error message:
    XML Parsing error: undefined entity
    Location: chrome://mozapps/content/profile/profileSelection.xul
    Line number 18, Column 1:
    <dialog
    ^
    Running on Windows XP SP3. No problem whatsoever before upgrading to 27. Sending this from Chrome as I cannot open Firefox at all.

    Thanks jschaer2000: after starting it once in safe mode, I closed Mozilla and tried several restarts in normal mode. So far, all worked:-)
    Thank you very much again.
    Still the automatic update process bothers me: it took me several days to discover the reason to the malfunction, since when I removed the problematic version from Add and Remove Programs, I didn't pay attention at first that it was another version, not v26 which I installed from my folder.
    In addition, I like to save the installation files before I run new programs and if I didn't have v26 exe file, I couldn't have operated Mozilla at all. Not that it was fun to remove and install again each time v27 didn't react, but it was better than nothing, I still prefer Mozilla over its competition.

  • Firefox will not start in normal (hour glass for a second) or in safe mode (closes after choice box).

    Firefox will not start in normal (hour glass for a second) or in safe mode (closes after choice box).
    I tried all of the following with no success:
    - uninstalling and reinstalling mozilla with no success.
    - End all firefox.exe from the task manager and then open again the firefox from quick launch or desktop or program files folder.
    - Change the firefox.exe name to firefox2.exe
    - Start in safe mode and choose several alternatives after choice box, but nothing happen.
    Please help.

    What is your computer system, and what Firefox are you using?
    Start your '''Computer''' in safe mode. Then start Firefox. Try '''Safe''' web sites.

  • Firefox will not open at all, no matter how many times I click it.

    Firefox will not open at all. I have tried troubleshooting, I have tried right clicking it and clicking "Run As Administrator", and I have tried uninstalling and reinstalling it. When i try open it, it does not come up with any error messages or anything. The loading icon appears then disappears, without firefox opening. Nothing I try opens firefox.

    You can
    1. Kill firefox.exe through the Task Manager, to open the taskmanager hit Win + R and enter taskmgr.exe in the window, hit enter, right click firefox.exe and hit "end all processes" or something similar.
    OR
    2. Boot into safe mode '''with networking''' and delete the Firefox install folder said above.
