Try to open and immediately get dialog box “Firefox has stopped working”. Event name: APPCRASH Version 65.0.0.6963

Can’t open in safe mode either. Have reinstalled five times and am having the same issues. Can’t access profiles.

What's your computer system and Firefox version?

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) Note: Check Both Folders

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

OS version: Windows 7 Enterprise Firefox version: 65.0.0.6963

Have done a clean install multiple times. Can’t open in Firefox “safe mode” nor when installing new version in windows safe mode.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
