Firefox crashes

Hello

After installing latest versions of Firefox (either 32 or 64 bit) the application will not launch. There is no shortcut to it on the desktop (which I asked the installed to create). So when I run it from C:\progfiles the screen just briefly flashes and nothing happens, it will just close the explorer window i had open and then nothing else.

I have tried uninstalling completely with Revo Uninstaller, rebooted multiple times, tried using offline 32 and 64 bit installers and the online one but the outcome is always the same.

Any help with this would be greatly appreciated.

Chris

Let’s do a full clean re-install; Download Firefox For All languages And Systems {web link} Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder.
https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac Linux: Check your user manual.

Do Not remove the profiles folder.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.

If there is a problem, start your Computer in safe mode and try again.

Ok so attempting the reinstall in normal windows yields no change in the behaviour. When I went into safemode though I was able to install and run firefox.

So i rebooted and went back into windows in normal mode and the firefox shortcuts now appear in the taskbar and on the desktop but double clicking them again yields the same results... firefox looks like it is opening but then shuts down straight away. Any other suggestions? I am running Windows 8.1 x64, tried running with Symantec disabled and enabled and both same results. Windows firewall is also disabled.

Regards

Chris

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}
