Firefox crashes at startup after installing update. Clean install does the same. I have followed the instructions in Mozilla help to this point - does not open in "safe mode" etc. Any ideas?

The issue seems to have resolved itself -- not sure why. Maybe update was not completely downloaded/installed??? Thanks!

Nooo. It's doing the same thing. It seemed like it was working again! But it's not.

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.

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

I did a clean install before i posted the question.

What I noticed is that either version (and I have now erased the old version from the applications folder) when opened from the dock crashes. It seems that the new version does not crash - as long as I do not open it from the dock.

Is that possible?
