I never had a problem with Firefox and now keep getting the following message
The instruction at 0x3f109352 referenced memory 0x00000000. The memory could not be read. Click on OK to terminate the program

Let’s do a full clean re-install;
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. 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 ++++++++++++++++++++++++++++ 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 if there is one.
After rebooting the computer, run a registry scanner if you have one. 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.

I am still getting the same message after your last instruction
That is too bad. Wonder if you do have a memory module that is bad. If you download this and make it a bootable disk and run it will check your ram for you. 5 passes should be enough I think https://www.memtest86.com/download.htm
It’s all getting too complicated for me now! I think I’ll just have to give up...I’m gutted as I use Firefox for work and it really was the best for what I do.
