[MinimizeToTray] 'MinimizeToTray' extension incompatible with Thunderbird 1.0.7

[Srikesh Sridharan]

Hello,

I am using Mozilla Thunderbird 1.0.7 (the portable version) and would 
like to be able to minimize it to the system tray.  Unfortunately, the 
extension available on the web 
(https://addons.mozilla.org/?application=thunderbird) is not compatible 
with this particular version of Mozilla Thunderbird.  Would you know if 
there is another version of the 'MinimizeToTray' extension that is 
compatible with Mozilla Thunderbird 1.0.7?  If yes, kindly direct me to 
the source.

Thanks much.
