"Good news everyone" - it took a while, but the bookmarks DID reload.
They are recovered. Praise the Lord!
And thank you Opera!
While I am aware that exporting and SAVING bookmarks (MANUALLY) is (supposedly) possible using the Opera browser for desktop/laptop computers, my question is:
Is there a way to export (and save to an html file) bookmarks from any of Opera's mobile browsers?
Real back-up always needs redundancy.
If you are reading this Opera developers, please understand:
Opera IS a great browser, but so many things can go wrong.
A simple export-to-html would solve the data loss risk, in my humble opinion.
