@oblomov No it will probably go towards some random service they'll launch or buy and then kill off a year or two later.
No money is allowed to go directly to Firefox development. That'd seemingly break some unwritten rule of our universe.
Regardless, I picked up a shirt and stickers because I still like promoting Firefox and Firefox-based browsers like Zen (which is the biggest contributor to most at my work migrating -- replacing their use of Arc). The less Chromium in the world, the better.
