Thanks for answer!!!

Thank you for the answer!
But I don't understand what it means?
Comp1: using every day
Comp2: using a couple of days a year
Want comp2(opera) to have all new stuff from comp1 when using it.
Using the same opera accont
Is it possible and if so...how do I do?

I have two computers where one is the computer I want to sync from (the other I want Opera to look like computer one)
The last time I synced it was the other way around and my main computer got all the old junk from computer two....took several hours to get it back the way I wanted it.
After that I haven't tried any more....
Maybe I don't understand how to do it, but the best thing would be if there was a "button" in the sync settings where I could mark which computer/opera should absolutely not be changed.

@cameronspringfield
A ugly solution thats works for me. I use "taskkill" in a shortcut in my taskbar.
ex. I have three monitors where I have Opera open....I press the taskkill (that I made to force close opera), next morning I start Opera and they start on all three at the same time.
One click to stop and one to start and I don't need to move tabs around.

@janmlar Ok, found a way my self....

Is there any way to start opera on 3 monitors/screens with one click.
I have a pc (win10) and 4 monitors connected and now when I start opera it start on one screen....then a have to take a tab and drag it to one of the screens and then again to the other...
Would be nice if there was a way to get it started on 3 (or 4) of my screens at the same time with one click.
