Disable default Thunberbird annoying Display
Images blocking (Display Pictures in Thunderbird by default)
Since quite some time I'm experiencing this annoying behaviour on
side of Thunderbird. Every time I receive a new mail which includes
embedded html code with pictures, Thunderbird blocks them until I
explicitly select the picture and allow it to display or either
allow picture displaying for the whole domain for the future
references. Today I decided at last to put an end to this boredom
and look for a solution.
Here is the way I changed this terrible behaviour:
1. Go to Thunderbird "Edit -> Preferences -> Advanced -> General -> Config Editor"
2. Look for the variables record mailnews.message_display.disable_remote_image
use the mouse to select "toggle" value to switch the default value from
"true" to "false".
That should be it.
