This post is a few months old, but even more relevant today. Every other product is jumping on board the AI wagon. I know I'm not alone in collecting a pile of bookmarks (mine is like an ocean! LOL), because... well, first I'm lazy but second the internal bookmark management is not that great.
Enter AI.
Firefox is probably already experimenting with AI internally, but getting AI to help you sort your bookmarks into some order, even based on directives or other instructions, is totally doable today.
I believe this functionality is important enough that it should be a part of the browser.
