so it just got installed in my PC and i don't know how......i have no problem with this app staying in my PC but whenever i try to open it, it says "could not find mozilla runtime". then i google it and came to this same site and it said that you have uninstall the app and again reinstall it but i cannot uninstall it. i went to the settings and went to apps and features but i cannot find mozilla firefox there. then i tried the other method which was suggested by this same site about going to the restart and type %APPDATA%\mozilla\ and then it said me to go to roaming and click mozilla firefox. i did that but when i opened it, it opened some other folder called "extensions". so i opened that too but the folder was empty. please do suggest something..

Are you talking about Firefox or something else?

As to Firefox;

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.

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.
