Why, after disabling all add-ons to correct a problem with Norton, am I unable to re-install Adobe Acrobat, even though all 7 applications in the "Containing Folder" are enabled?

more options web page began coming up whenever I would go on line. Norton email support gave me steps to follow using my Firefox browser, in the safe mode, to disable all add-ons and reset user preferences to Firefox defaults. Since then, although trying about 15 times, I have been unable to reinstall Adobe Acrobat so that it functions. From the "Re-initializing the plugins database" article, and progressing to the "Open Containing Folder," but unable to select File and Exit menu, I did locate "Adobe Acrobat" version which showed all seven applications "enabled." This problem is with Firefox only. Internet Explorer functions normally.
