What happens when you try to uninstall? Could you tell us the specific error message?


These are four folders where the Firefox program files may be stored. You might only have two of them, depending on 32-bit/64-bit versions and timing of your installation.

C:\Program Files\Mozilla Firefox C:\Program Files\Mozilla Maintenance Service C:\Program Files (x86)\Mozilla Firefox C:\Program Files (x86)\Mozilla Maintenance Service

Firefox data is not stored in those folders, it is stored under your Windows user profile. Please see: Profiles - Where Firefox stores your bookmarks, passwords and other user data. And to explore you may need: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

i can't remove mozilla firefox C:\Program Files\Mozilla Firefox C:\Program Files\Mozilla Maintenance Service C:\Program Files (x86)\Mozilla Firefox C:\Program Files (x86)\Mozilla Maintenance Service because the computer i have requires administrative permission. it let me delete the file contents,but it won't let me delete the files. does this mean i have empty files taking space on my hard drive? how can i get rid of this crap without admin permission? the computer came from a school,and the codes i was given don't work,because they did away with the damn admin crap.

Do you mean you can remove all the contents of each of those folders, leaving just empty folders?

Empty folders do not take up any amount of space worth worrying about.

If you own this computer now and need to refresh all the permissions on it, try a Windows forum for advice on how to do that without having to reinstall everything from scratch.
