Review for MinimizeToTray by luettenprinz
Rated 4 out of 5 stars
Warning!!
Link from Mola-Cho seems to be rubbish: links up to two pay for click sites and than to a file on depositfiles that is too big to be the real extension (5.17 MB! instead of 42 KB!!)
I have downloaded the zip-file: inside is some obscure mp3 file named "Vanessa Mae - The Havana Slide.mp3 "
Besides, the extension is good, but not compatible with firefox 3.0.5.
