No

I just want a web browser that doesn't need to be restarted occasionally, to avoid slowdowns.

In both Blink and Gecko engines, if I don't close and re-open the web browser after 100 or so hours of use, I can close everything but a single tab in a single window, and it'll be laggy, but if I restart it and restore to the same tabs, it's perfectly fine.

I'd switch browsers if a chatbot was somehow forced on me.

A conversational interface in a browser doesn’t make sense.

AI in browsers makes sense when it’s a feature integrated into search results.
