Hi!
I'm currently using Opera GX, but I also had this issue with the regular Opera. Thing is that when I check the "tabs" option to see the tabs I have open in different devices, there are so many versions of the same device. There is this device called "ARTS-T", it's only one computer, but many times I turn on the computer and open the browser it's like each time a new group of tabs is generated from the same ARTS-T so it's uncomfortable for me, because if I open Opera from another computer and want to check what I have open on ARTS-T, then G*d help me find the correct ARTS-T. This didn't happen before, but it's been happening for a few weeks now.
What can I do?
