do you still see this problem on a newer 2.x release or a beta of 3.0?

Is this the same bug?
Windows Vista. Thunderbird version 16.0.1.
method:
right click on jpeg image attachment
choose Save As
Window opens, I choose the folder where to save
the 'filename' has automatically remove the extension, so attached image called IMG123.jpg is now called IMG123.  The 'Save as Type' says 'All files' and this is the only option.  When you click on Save, it saves to the designated folder, but looks like a txt type file icon. When I try to open, I'm asked 'choose the program you want to open this file'.
If I 'Save as' and reinsert the .jpg so that it says 'IMG123.jpg then there is no issue.
This particular problem started immediately after upgrading from 15.0.1 to 16.0.1.
