Ok, first, do you have permissions to update Firefox on that computer (are you the only users, have admin, etc.) If you aren't an admin you won't be able to update firefox (or if you are using a program such as deep freeze to lock the computer down).

Then, if you are the admin, use http://ninite.com/firefox-flash/ninite.exe to download Firefox 18.

After that, read Websites say that Firefox is outdated or incompatible even though it's the latest version

If there are problems with updating then best is to download the full version of the Firefox installer.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
