@dipardor Same here. And I'm using Developer version on Windows.

@lucas81 There isn't such feature.

@twolff-wescale If it works in a standalone installation, but not in a regular installation, that implies that there's something messed up with your Opera profile for the regular installation or that something external is interfering with Opera when it's install in its default location.

@dragoncat I'm not sure if it's possible.

@jasyalstr14 Since you posted in the wrong forum, please tell of what Opera you are talking about, so this topic can be moved to the correct place.

Well... As Mac-2 is on the way to repair service, I decided to purge the HD and reinstall the MacOS operating system, altogether. With Mac, its not such a big deal as with Windows. But one only needs to do it in very rare occasions - like now, when I'm testing a heating problem of Mac-2.

After the OS was installed, I downloaded Opera and logged into sync. And now I can see all three devices - Mac-1, Mac-2 and Windows-PC open tabs, bookmarks and speed dial.

I guess we can call this case solved, even though we don't know what caused the problem, initially. Thank you @lecog for your help, and let's carry on from here. Have a great summer and stay healthy!

over and out!
