i wont do that because of several (personal reasons). either user himself or nothing, but a HOSTS file for the main crap, by remote. firefox and chrome have powerful filters and block lists, not comparable with uBo. too many not savvy users may get annoyed and disable or uninstall the ablocker because they cant get along with it. i know a lot of users which use uBo in simple mode "matrix!" "what?", "Picker" "yeah, ice picking" "wtf", i dont mention netlogger... most people using another antivirus than defender are not aware, that such programs insert extensions in a firefox profile.
