Rated 4 out of 5 stars

Very valuable add-on. One drawback, however, is its unawareness concerning date change. If firefox is kept running for more than one day, the history stack won't be shifted after midnight.

This review is for a previous version of the add-on (2.1.2.1-signed).  This user has a previous review of this add-on.

I have tried to set the clock to 2012-12-31 23:59:00, cleared all history, opened few pages and confirmed the Today folder contained those pages. Then I opened the history menu and just waited for the day passed. When 2013-01-01 came, the Today menu didn't change. But I clicked elsewhere to close the history menu and opened it again, the Today menu updated to Yesterday. Everything works just fine in Windows, Firefox 20.
