Firefox will not start after the upgrade to 27. Seen an error message during the upgrade process, but do not remember.
Tried running firefox.exe Pei but error message:

XML parsing error: the undefined entity
Location: chrome://mozapps/content/profile/profileSelection.xul
Line 18, column 1:
"< dialog < =" "^ =" "p =" "> < / dialogue >

Running on Windows XP SP3. No problem whatsoever before moving to 27. Sending of Chrome that I can't open Firefox at all.

Thank you, jschaer2000. In the meantime, he works. How long, we'll see ;-)

  • Firefox does not start after the places.sqlite opening in Notepad

    Firefox does not load again. I tried to create a large folder of bookmarks, but I wanted them to hide so I tried to be clever and create a copy of my current places.sqlite who had no bookmarks added and moved elsewhere, then I added bookmarks and once that replace the current places.sqlite then I created a copy of this and put it elsewhere for more security and then I replaced it with the first places.sqlite I had copied. I had to go through that much trouble because for reasons, I was unable to delete the bookmarks by right-clicking and selecting delete. I had already tried to open places.sqlite in Notepad and since then is when it started to happen. I tried to reset the file extension type, or rather detached, but I can't figure out how. I also tried to remove completely any Mozilla partner, restarted my computer and then reinstall Mozilla, but it didn't work and I prefer not to try again or uninstall it because my computer has a very difficult time even boot Windows 10. He likes to get on the desktop and then never hang while I have to restart the computer continuously until it works.

    Can someone tell me what to do or where it is that I was wrong?

    Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

    If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

    If you keep the problems, and then create a new profile.

  • Computer will not start after the installation of Kaspersky, will not even go into safe mode

    I tried to install Kaspersky on my laptop this morning to roll some viruses on my computer. After you restart during the installation, I got the blue screen of death with a STOP 0x000000F4 error code. I can't use my phone at all now, and it will not work in SafeMode either. I tried to restore the computer to before that Kaspersky was installed but it cannot do so. I tried to restore to the last known good configuration, but that did not work. I have no idea what to do now. My laptop is basically useless now and I am very angry.

    If I have the Kaspersky disk in I kind of access Kaspersky, and it keeps telling me it is obsolete and must be updated, but it will not be updated. Also, it tries to mount the drives or something and gets stuck trying to create the swap file. I don't know if it's important, but I'll post it anyway.
    I'm at a loss to know what to do...

    If you have tried to install an AV program after your PC has been infected you left it too late.

    Your safest option is to use your recovery discs to get destructive if you plant (make sure that the external devices are disconnected during this process)

    I hope that you, the data has been saved you will lose everything on the PC

    Once recovered allow windows update to do its thing for Important updates ONLY. It may take several reboots.

    If any update fails cure this problem before doing anything else.

    Once the update finished visit of manufacturers of laptop for important driver updates to update necessary.

    Only after this has been done, you should start installing software or external devices.

    If an installation fails, solve this problem before

  • Firefox does not start after the update?

Then, when I clicked on my shortcut of firefox to open the browser and restore my previous session, he said that the browser has been updated and that he would begin shortly. He never did. A few minutes later, when I tried to click on the usual shortcut I now get the message "the"firefox.exe"item that this shortcut refers has been changed or deleted...". »

  • Satellite L300 - will not start after the installation of Skype

    My Toshiba Satellite L300 won't start after installing Skype.
    This happened to someone else, and can I do?

    Thank you.

    I think Skype is probably the most used messenger and ideal application for communication.
    It is professionally designed and programmed. As you know in recent years, it has been offered in many different versions and it is always better and better.

    So I think that Skype itself is probably not the problem. I know that a lot of people also use Skype and I've never heard problem described.

    Anyway, what you can try is to remove Skype and try to install it again. Try also push the BONES at that earlier time. Maybe some Microsoft updates are responsible for the stability of the software.
    It's really not easy to say what the problem is here.
