Macbook downloads won't open and all have the file name "firefox"
I factory reset my macbook a few weeks ago. I re-downloaded chrome and firefox with no issues. Now, it can't seem to download anything on any platform. No matter what I download it shows up on my desktop as a device that can be ejected but will not open and also has the file name "Firefox". I am losing my mind here! Why is this happening? How can I fix this?
MacBook Air (13-inch Mid 2012), OS X Yosemite (10.10)
