Update: Mozilla Thunderbird 2.0.0.18
My favorite email client, Mozilla Thunderbird, has been updated to version 2.0.0.18.
Unfortunately, it’s a just a YABR (yet another bugfix release)… I think Thunderbird really deserves a full update with new features, but it looks like we’ll have to wait some more for that
