871875 - dragging JPG image into Thunderbird compose window inserts as inline BMP

Status: RESOLVED DUPLICATE of bug 871873

(Firefox :: Untriaged, defect, P2)

Description

[Lee Binder]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0
Build ID: 20130409194949

Steps to reproduce:

From Firefox 20.0.5 32 bit Windows virgin account (no extensions), dragging JPG image into TB virgin account (no extensions) compose window

Example: http://www.vitaminlife.com/images/products/huge/033674632000.jpg


Actual results:

the image gets inlined as BMP.

Resulting Problems:
1. not all (if not most) email clients display .bmp
2. inlined grfx and therefore sent email size is unnecessarily high


Expected results:

.jpg image should be inlined as jpg

This works fine if the .jpg is dragged from Internet Explorer 9.0.15 32 bit (Windows 7 64bit), so this might rather be considered a Firefox than a Thunderbird bug. On the other hand, when dragging the .JPG from FF to Desktop or Explorer, the extensions correctly remains .jpg 
-> seems we're dealing with a drag/drop miscommunication betw. TB & FF here.

1. I'm running 32 bit versions of both TB & FF in my Win7 64.

2. I changed priority because recipients cannot see these images

3. Workaround:
a) in FF, copy URL
b) in TB, Insert/ Image/ paste image URL
