Someone needs to convince Firefox rather than develop its own AI (https://news.ycombinator.com/item?id=45926779) to develop a system to pipe your html rendered browsing history in real time so external local services can process it (https://connect.mozilla.org/t5/ideas/archive-your-browser-hi...). See https://news.ycombinator.com/item?id=45743918
Firefox probably won't suddenly have the best AI, but they could have the only browser that does this.
They'd probably reject that idea under some bullshit privacy or security excuse Wayland-like reasoning. Also why we don't have XUL extensions anymore and why they'll eventually copy chrome on that manifest crap.
