Hi, my name is Dan. Have enjoyed Firefox for over 17 years. I have uninstalled and reinstalled latest Firefox 4 times. First 2, dialogue box appeared, cannot locate VCRUNTIME 140_I.dII, continue install. Second 2 attempts, did not appear. Now cannot sign in. Click login, opens tab but nothing happens. Click options nothing happens. Have checked firewall settings. Have tried USB Debubbing with Android Firefox and Firefox Nightly, both said to be incompatible. Stay Safe. Thank you in advance .Kind regards, Dan
If you want to reinstall Firefox, follow the instructions below. If you just want to remove it, disregard the install instructions.
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.
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. 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 ++++++++++++++++++++++++++++ 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.
