I just(Jan 24, 2010) downloaded this after searching high and low for the missing columns in TB3. It installed smoothly and flawlessly without issue #1. Now my folder columns are back in place exactly as they were in TB2. Something Mozilla should have left intact initially. But Moz still rules so one should consider this TB3 omission as a minor oversight that was quickly corrected by this add-on's author.
