Add-on has not functioned since TB 52. Button is not in toolbar, option is not in menu. Developer is unresponsive to contacts. It's a shame, because when it worked, it was wonderful. This feature should be part of TB by default and not forced to be provided by a third party add-on. Instead, Mozilla forces Lightning on us.

It's simple and straightforward—you just install it and add the columns to the view, and it just works.
Unfortunately, it doesn't work in Unified mailboxes. It simply comes up blank there. The developer posted a response to another review back in May 2014, saying that making it work in Unified views would be in the next version, but there hasn't been a new version release in that 18-month period.
Since I'm managing ten different email accounts at once, this add-on is almost completely useless to me until it works in a Unified Inbox. Three stars because it works exactly as it's supposed to. Add the Unified compatibility, and it would be five stars, no question.
