Since you run version 36 and looking at this question, what happens when you install version 36.0.1 if not using it already?

Additionally I’d think of running a System File Check (sfc.exe) as suggested there.

hi, that's unusual. next to the security software already in place, can you please run a scan with various other security tools like the free version of malwarebytes, adwcleaner & eset online one-time scanner and see if they come up with some stuff?

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. 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.

Let me see if I got you correctly before I judge your respond since I am not so tech savy. I have uninstalled firefox, then removed traces of it, from register and Program 86x, then reinstalled firefox. If that is what you are trying to say, it has not worked at all!

I have run a system resort point before the problem occurred and reinstalled firefox (version 36 - the one I like) Now I am getting a new error message as follow The program can't start because "mozglue.dll" is missing from your computer. Try reinstalling the program to fix this problem.

You need to do a full install because that file is missing.

https://support.mozilla.org/en-US/kb/install-older-version-of-firefox?cache=no Be sure to read everything here.

If you still want to downgrade, look under; I still want to downgrade. Click the Directory of other versions and languages link. Look for the directory of the version that you want. But, remember that old versions may have security issues.
