Firefox always asks me where to save a file. I set it that way and I want it that way.
However, it pops up an additional unnecessary dialog box asking me that to do with the file: 'You have chosen to open xyx.exe file' which is a binary file. Would you like to save this file?. The choices are 'Save' and 'Cancel'.

Only after this it asks me WHERE to save the file.
How do I get rid of the first dialog and jump directly to the second one (where to save)?
