Any time I download a setup.exe file the file extension is changed to setup.exe.part. The executable won't run to do the install. I've tried the same executable downloads with other browsers and it works fine. Suddenly Firefox seems to be altering the file I'm downloading. 1. I use the Download Manager and download to the Desktop (as I have chosen in "Tools". 2. I always save the file since the "Run" button is not available when starting the download. 3. The file for some reason now always saves as xxxx.setup.exe.part 4. The executable will not open and I always get an error dialog that offers me a search on the web to try to open the file. Please help. Thanks
