Thunderbird (the email client) was spun off from Mozilla Corporation into a new for-profit company called MZLA Technologies. Both corps are still subsidiaries of the Mozilla Foundation. Thunderbolt is a new product from the MZLA Technologies team.

I am a happy Thunderbird user. But when I see such reorganizing and deliberately confusing naming, I assume that there is somewhere intent to deceive.

TIL, thank you.
