Thunderbird its very old

[wonder]

@wonder: so lightning works fine for you?

Yes, works fine for me.

But, I explain with detail:

In days ago, I have TB and Lighting, I update TB from the TB website (not from any ppa, directly, I download TB from website of TB), are the same version that now, Maui are updated.
Works with this version.
I made backup of my .thunderbird folder of my .home.

I made a fresh install of Maui.

I update all my system, and Maui update TB to 45.3.0 (same version of TB website).

I restore my backup (.thunderbird folder to my new .home folder).

In this moment, start per first time my TB.

All in TB works fine, Lighting works fine for me, and not have any error message about Lighting.

Regards.
