"Message Archive Options 5.0.0 could not be installed because it is not compatible with Thunderbird 3.1.13."

Where to find the right version of this?
It cannot be found at all from inside Thunderbird.

Αυτή η αξιολόγηση γράφτηκε για παλιότερη έκδοση του πρόσθετου (5.0.0). 

That's because 5.0.0 isn't compatible with TB3.1.13. Install an old version for your old version of Thunderbird!
