So, what I'm asking is if the Firefox powers that be, update the steps to coincide with end users.

Hi

1. Access you account at https://accounts.firefox.com/signin and remove all Connected Services that is not your iPhone.
2. Wait a good 20 minutes or so.
3. Browse a few sites in Firefox for iOS, save a few bookmarks and in the Firefox for iOS settings force a manual sync event.
4. Sign into Firefox Sync in the desktop copy of Firefox.
5. Wait for your data to come through.

I recommend taking a backup of your desktop Firefox profile once all your bookmarks and other data have arrived.

Thanks for a reply from what may or may not be a major browser. The work around is a generous suggestion and your time is appreciated. Backups still remains a problem, as without desktop Bookmarks, endusers cannot backup from the phone. Phone backup will be needed before moving to a new browser, whatever that may be.

Inadvertently, I woke up this morning and the desktop was automagically (nice, but without my control nor permission) populated from the phone's bookmarks, somehow (...Palpatine returned?).

However, the fundamental challenge remains outstanding. The workflow/process/steps are incorrect and new Firefox users like my earlier self, may lose their sole phone Bookmarks data. 'Tis perhaps elitism as there seems to be a massive but silent community to fine tune the UX needed to welcome new users, if they're welcome, but perhaps not?

I guess Github co-founder's Ladybird Ladybird has an opportunity for market share handed to them on a platter? (I still don't understand the need for yet another browser, seems like 1st world problems, aside from the frustration of slow moving large organisations which seems to be the case of today's Firefox).
