Rated 5 out of 5 stars

Works great with FF3! after you make a few changes.
It works.

1. Open xpi file with winzip. (I right clicked on it and hit "edit" instead)
2. Open install.rdf and change -> 3.*
3. Save all.
4. Install modified xpi file...by opening FF3 and go to File, open file and then minimizetotray-0.0.1.2006102615+-fx+zm+sb+tb.xpi
