"All three guys, was your Opera set set as the "default browser" prior to the "update"?"
I had both Opera 12.17 and 24 installed.
Opera 24 was updated without any notice to 25.
Apparently Opera 24 was set to the default browser and that carried over to 25. So no, 12 was not set as the default before the unannounced update. 12 had been having problems displaying some newly revised websites, so I used it for some things (working with my bookmarked sites, and used 24 for other things.
And after I reset 12.17 to my default browser and went to opera://flags/#first-run-import and enabled the first run import, it obviously doesn't work.
So Opera CAN import the bookmarks but ONLY if the user has ESP and knows in advance of the update and in advance of the first run that they have to set their preferred browser to be the default browser.
And now, even though the ability is there, it's too late and we have to wait (months?) for the next update.
How does that make any sense? Why should the user have to have expected that?
