I see #mozilla making all these #ai related announcements and it makes me sad.

We need you focused on making #firefox the world's greatest web browser.

We need you to curb stomp #chrome and #edge and all their sleazy shenanigans1.

There are so many areas for improvement but I'm going to list a few anyway:

Better support for multiple profiles. Trying to use multiple profiles in Firefox right now is miserable #ux sadly.
WebUSB support
Fuller WebGL support

(With apologies to the folks working on those teams. I'm sure you're good people, but these products are super sleazy in the form they ship to the world)
