I'm using Thunderbird 3.x on Ubuntu (Linux). When I save an attachment to my computer, the file gets saved with only the owner (me) having read/write permissions. In other words, the file gets saved as -rw-------.

Frequently, I want my group to have permission, or to give read permission to everyone. Is there a way to do change Thunderbird's default file permissions so I don't have to do this manually every time?

Its a bug and it is supposed to be fixed in 3.3: – Moritz Both Feb 8 '12 at 9:17

The application should be using what umask is set to.

What is the output of the following 2 commands ?:


cat `which thunderbird`|grep umask

umask is 2. The 2nd command returns nothing (no output). – Eric Heikes Jul 2 '10 at 3:13
