Thunderbird 7 on Ubuntu Oneiric

[Mike Conley]

Mihamina:

The default theme for Thunderbird was modified per Canonical's request, 
in order to make Thunderbird fit in better with their default theme. 
This was one of the requirements for making Thunderbird the Ubuntu 
default e-mail client.

If you'd like to get the original icons back, you have a few options:

1)  Download and install Thunderbird directly from Mozilla, and bypass 
Canonicals packaging.

2)  Install the "GNOME" or "Humanity" themes for Thunderbird.  I just 
tested them, and they revert the icons.  Currently, you'll need to force 
add-on compatibility (either with the Add-on Compatibility Checker or 
Nightly Tester Tools add-ons).  Please note that I have not thoroughly 
tested these themes, and they might break the appearance of several 
interfaces in Thunderbird.

I hope that helps!

All the best,

-Mike

Hi all,

On Ubuntu Oneiric, the thunderbird 7 icons are those black ones:

I expect them to be the old ones, more looking like GTK icons.
In the settings (tools, addons, apprearance) Default 7.0 should be the
ones I want. But in fact, they are those gray ones.

Is this because of a third party Ubuntu package overriding the apearance?
How to get the default buttons back?
