I get it but, if it’s maintained by a different party then Google, even then there’s going to be some conflict of interest compared to Google’s Chrome and Brave’s Chrome for instance.
But if you would rather use the ai features in Firefox, then have at it. Falkon doesn’t have any mention of ai in it’s settings or features. Nor does it have an ad network. Sometimes you got to look at more then just “it’s based on Cromium.”
If it keeps out the ai features in the latest updates and the ad networks, then that fork and some of the other Firefox forks might be a good option.
