If that is not the case, the Number of pages in the session history may have been set to zero. To check that, select "Edit" -> "Preferences" -> "Navigator" -> "History". Check what it says under "Number of pages in session history". If the value for that is "0" (zero), this is the reason for the back and forward buttons being greyed out. The value (number) determines, how many previously visited (in one session and one browser window/tab) pages will be accessible via the back and forward buttons, i.e. if it's at 20, you can go back and forward 20 steps. Please note that you will have to restart Mozilla before changes to this setting take effect.

After some digging ctrl H is your friend I found the original link I meant to paste.
A funky theme could cause that behavior. Look through this thread you may find what you are looking for

Thunderbird doesn't have a bug...it's just that Mozilla doesn't really explain its software that well.
Anyway...I was going through my Trash, in Thunderbird, and decided to turn the Message Pane on: View/Layout/Message Pane. After selecting one of the e-mails I wanted to view...low and behold, the Forward and Back Buttons were no longer grayed out.
So...in answer to your question...they work, but you have to have Mesage Pane enabled...and you have to physically click an e-mail in the folder before it works.
Hopefully this has resolved your issue...
Can I get ozzie's points? LOL!

The only thing that worked for me is by using the B and F keys. Pressing those keys on your keyboard will step through the messages as I expected the buttons would do. Perhaps this will be sorted out in a later version of TB.

I know this thread is old but maybe peeps are still looking. These buttons only work at specific times. eg.
5 emails com in, you look at no1, then no2
You can go back from 2 to 1 or forward 1 to 2, they have to be current emails in this session you have viewed.
Now view email all 3 to 5
Now you can back from 5 to 1 or forward 1 to 5 no others.
Should you then look at another say 3 emails that were already viewed in the past it will add these to the back and forward sequence. Close and reopen Thunderbird and no forward or back available untill you look at some more old or new emails. as I said they are session related.
