[OpenIndiana-discuss] Thunderbird update to 78.8.1 imminent

[Andreas Wacknitz]

Hi all,

as you already might have noticed we have updated our firefox to a more
recent ESR version a few days ago.

A similar update is imminent for thunderbird. Unlike for firefox the
thunderbird update to 78.8.1 might cause troubles for you as the profile
format has changed between the versions.
So, after updating to the the new version there is no way back other
than having a snapshot or backup of your users' thunderbird profiles.
They are typically located below ~/.thunderbird/.

Old profiles also might seem to be invisible after the upgrade because
new profiles have automatically been created during first start of the
new thunderbird.
In a situation like this you might want to start thunderbird with the
profile option -p: "thunderbird -p". With this you should be able to
switch between profiles.

Furthermore, it might be necessary to re-enter mail account passwords
after the update.

Special thanks to Carsten Grzemba who made both updates possible.

Kind regards
Andreas
