Firefox crashes on Mac OS Mojave 10.14.16

Hi, I have the latest version of Firefox (68.0.2) and it crashes every time I run it on my Mac (Mojave 10.14.16). It does that in normal mode as well as in safe mode. I tried refreshing Firefox as well, but the problem continues. I also tried downgrading, no change. I would be glad for any ideas, as I have been using Firefox since like 2007 and I really don not want to change to another browser. Thanks.

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.

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.

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;

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. ++++++++++++++++++++++++++++ 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. This shows how to Start all Computers in Safe Mode; Free Online Encyclopedia

Hi, the full clean re-install does not help. But Firefox does run in Mac safe mode (safe boot), or at least it does not crash - due to some restrictions in the safe mode, I guess, it does not appear properly and you can't see any tabs and can't click any links, but it opens and stays open...

That means something on your system is causing trouble. As a test, disable your protection programs.
