I've turned off Thunderbird's "Global Search and Indexing" over and over again. I've deleted the global-messages-db.sqlite file more than once.
This works for one session, but as soon as I restart my computer, Thunderbird goes back to using the Global Search and Indexing. (Though it looks like it isn't being used under Preferences.)
Any ideas how I can get Thunderbird to remember? Thanks so much.
