My firefox doesn't recognize .docx or .xlsx files. They both come up as the same thing -- a Chrome HTML document. Since it isn't recognized, neither Word nor Excel are drop down options as programs to use to open the file. I have to manually browse and find either Word or Excel each time. If I keep opening excel docs, its ok because the Chrome file "remembers" excel, but if I then open a .docx file, I have to go in a search for Word again. When I go to options to change how an application is opened, its the same thing. I can't find a way to make firefox recognize .docx and .xlsx files as anything but a webpage let alone 2 different types of files. Can I manually add those as features? I tried using add-ons but that didn't work either.
