I try to follow this discussion (unfortunately I can't contribute), but it's kinda not clear (well maybe guessable) whether what you're saying is about Firefox or the Sailfish browser (how about we call it Sailbro! I'm gonna do that now). In the first paragraph you are referring to a question about Sailbro, then you're answering it about Firefox? Other than both using Gecko, do they have enough in common for that? I gather the question is: can we, and if yes, how can we get things that work in FF to also work in Sailbro? E.g. make Sailbro sync with Firefox (that would be so cool), or set a custom default search engine. Is that the topic here?
