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.

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.
