The buff reminder add-ons we found with a Forever file are Opcow's Buff Reminder, Thanks for the Buff and Manners. BuffReminders and 
WeakAuras had no Forever file when we last checked on 2 November. Each name links to its add-on page, which shows the current status.

These descriptions are the authors' own, so check that your buffs are covered. We haven't tested them on the live client.
Which to pick
- You only want a nudge before a pull: Opcow's Buff Reminder.
- You want to click and cast the missing buff: Thanks for the Buff.
- You like to return buffs in town: Manners.
- You just want to see how long a buff has left: BuffTimers.
The combat limit
Blizzard's combat rules for add-ons, written for Midnight, let them display combat information but not read it or act on it, and Forever appears to follow them. So treat any of these as a reminder between pulls, not a live tracker in the middle of a fight. See Battle Shout reminder for that in more detail, using one buff as the example.
Without an add-on
Put your buffs on a key you press out of habit before each pull, and keep the default buff row in view. In a group, agree who's covering what, as it's easy to double up.
Class-specific picks are on the best add-ons by class page.
