Firefox keeps asking me what program to use to open file types even though I have selected one and checked "do this for all files of this type" going foward

I am working in Windows and every time I open an attachment, Firefox asks what program to use to open files of this type. I always select the proper program and then check the box that says use this program for all future files of this type. In spite of that, the program continues to ask for every file. How do I turn off this feature and just have the program remember the correct program to use for each type of file extension?

Regardless of your download preferences, web servers can trigger a download prompt by sending either the Content-Type: application/octet-stream or the Content-Disposition: attachment header. You can check if that's the case by examining the server response headers in the Web Console.

For the latter problem install the InlineDisposition add-on and see if it helps.

If the problem persists, post back here with either an example link or a screenshot of the relevant response headers in the Web Console.
