Rated 5 out of 5 stars

Actually, if you click on the link below under Release Notes, you can get the Experimental Version (Version 0.5.7.5 — October 1, 2009 — 183 KB) that seems to fix the problems with logging into multiple accounts. At least, it works fine for me on 10.12.09.

This review is for a previous version of the add-on (0.5.7.5).
