Firefox may not be running visibly but is probably running in the background. It is in the task manager. To access the task manager go to Start and type in the search field taskmgr. That will open the Task Manager process. Then go to Processes tab and end firefox.exe. After ending that process, close Task Manager and try running the installation/uninstallation again.

You should update to the latest version. See Update Firefox to the latest release
