'never update' checked, still updates

more options

Last week Thunderbird updated and 'broke' my folder sort order, which I rely on. (Thunderbird sorts alphabetically only as of years ago, needs an add-in for manual sort, this update broke the add-in.)

I rolled back to 52.9.1, redid my add-in & manual sorting, and checked NEVER CHECK FOR UPDATES.

Today Thunderbird updated AGAIN, AGAIN losing my sort order.

Why did it update when NEVER CHECK FOR UPDATES is checked, and how can I stop it from updating again??

In the graphical interface, NEVER UPDATE is still checked. Looking at app.update.auto, it is FALSE.

Yet still it updated.

I've never noticed any TB settings being reset automagically by 3rd party sw - doesn't seem like that happened here either.  :(
