if anyone knows how to edit the 3 dot menu on any android firefox based privacy focused browser please tell

from that, i understand that what you want is a way to edit the menu in any firefox-based browser. where in that do you ask for a fork of firefox?

did you mean to say something like "does anyone know a fork that has an editable 3 dot menu?" or something similar?

if that's it, it's a better idea to go in a firefox community and ask for that there in a post, since more people are going to see it in a post than in a comment.
