After the latest update, I can't open Microsoft applications. I have to save them to a file. When I get an email with a Word or Excel file attached, I HAVE to save it. Before the update, the system always opened it so I could look at it first. I went to settings and Applications, but in the window where it says, "Choose how Firefox handles the files you download from the web or the applications you use while browsing." There are no Microsoft options. I was able to change the PDF docs to open rather than save, but I need to do the same thing with Word, Excel, PPT, etc. Please help
