Just an update on handlers.json

[DanaMW]

My original suggestion of deleting handlers.json is or was good but I seemed to have to re-delete every so often so I decided to work up another solution. I loaded handlers.json in notepad++ and used the add-on json formatter to format it readable then i added the mime types to it myself. It always seems that *.exe files went to the browser no matter what i did so I added:
"application/exe": {
"action": 0,
"ask": false,
"extensions": ["exe"]
},
"application/octet-stream": {
"action": 0,
"ask": false,
"extensions": ["exe"]
}
Now it grabs and sends them fine I added like mp3 and mp4 zip pdf and others I download to it too. Working perfectly now.
as for what the action are... and zero is what you would want i believe.
0 = Save To Disk
1 = Always Ask
2 = Use Helper App
3 = Handle Internally
4 = Use System Default

Hope this might help someone else. Oh and here is a listing of the mimetypes if you need them,
