I have a program which I use exclusively on Firefox and until a few days ago I could open the rtf files which I downloaded on MS Word. Suddenly they won't open. I was told to go to the settings >In Firefox Settings>General, under the “Files and Applications” section, be sure that RTF files are set to “Open in Word” There is no rtf listed there as a file type. Did something get changed recently? This is a massive problem for me. I really hope you can help. Thank you
