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.

Thanks Fred. I had problems from the get-go with trying to add .old to file folder names. The computer kept jumping away from the page.

One of the problems with the HP STream is really restricted space so I tried to download Firefox again but store it on a thumb drive. It basically got stuck in some infinite space and didn't complete in 15 minutes so I cancelled the download.

I freed up some space by eliminating a bunch of previous downloads with .exe (assuming I had installed them already).

Should I just delete all of Firefox/Mozilla and start up again (by way of the microsoft web browser? I hate to lose all my passwords etc.

I'll try again via thumb drive to download Firefox and hope that when I will install it it will ask if I want to replace current copy. Sound like a plan?

Also I have Mozilla Firefox and Mozilla Maintenance SErvice programs in the file. Lots of folders and separate documents. Can I delete any of these?

Firefox comes in two or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And at least one folder in the profile of each user on the computer.

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

First, download the current Firefox and save it.

The reason my instructions say to rename the original files is so that if we want we can look at those files later. In one case, part of those files were corrupt because the hard drive was corrupt.

Remove all Mozilla and Firefox folders from the Programs Folder. Windows: C:\Program Files C:\Program Files (x86) Note: If there is a problem, start the Computer in Safe Mode. Once the folders are gone, reboot the computer.

The Mozilla Maintenance Service is used for downloading updates in the background, so you should leave this program.

As it turns out I found the solution elsewhere on the internet. The problem is that other Firefoxes were still open in the background although I had closed out Firefox and even turned off the computer. I ended up right-clicking on the task bar, finding the Firefoxes that were running and right-clicking to turn them off. Then downloaded Firefox again and it went smoothly. In the process, to try to solve the space problem, I deleted all previous downloads. These HP Streams have zero space to spare. Thanks for all the suggestions!
