@Mayfly My problem is solved! You can find my solution at the end of this conversation.

@leocg My problem is finally solved! I first installed the Opera GX browser on my computer, logged into my Opera account on both Opera One and Opera GX, and enabled synchronization. After making sure that all my settings, passwords, bookmarks, etc., were exactly the same in GX, I tried reinstalling Opera One. When that didn’t work, I uninstalled Opera One and reinstalled it again without deleting the user settings, but still no luck. Finally, I uninstalled Opera One completely, including the user settings, then reinstalled it—and Aria finally appeared! I logged into my Opera account on the newly installed browser, activated synchronization, and everything was back as it was before.

In short, fully uninstalling Opera seems to be the only way to fix this issue. While I could have synced with Opera on my phone or used Opera Portable, as you suggested, I chose GX since I’d been meaning to try it anyway.

Thank you for your quick replies whenever I reached out with my issue. I hope my experience helps others with the same problem.

Have a great day,

@leocg no because I have so many bookmarks, full of bookmark bar, passwords and so on. Even I can backup these, I'm worried about the order and locations of bookmarks getting mixed up, if there is a way to get everything in the browser exactly the same with one backup I can try.

@leocg after a month from my latest message there is no change. Now my opera version is Opera One(sürüm: 114.0.5282.115)

I can't seem to enable Aria. my browser is the latest version (i'm in Turkey). I can use Aria on my phone but not on my pc.

When i go to the settings menu > ai services, i can enable chat gpt and chatsonic and they show up in the sidebar instantly. When i enable Aria in the sidebar no icon shows up. If i come out of settings and go back in again the Aria in the sidebar option is once again deselected.

@leocg I can understand for some internal pages like "settings", "history". But "bookmarks"? We should be able to open it with its button. If we can't use opera's properties in private mode than what's the point for use this mode? It's useless. Opera has to fix that. With some stupid upgrades Opera will start to lose users. And it's not an upgrade, it's literally degrade.

This is a new problem. Start after Opera upgrade itself. When I am in the incognito window I want to open bookmarks. But when I press the heart button for this it didn't open in the incognito window, it opened in a new normal window automatically. Previously just "settings" was opened just like that. But now "bookmarks" too. I want to open bookmarks in the incognito window. But I can't find any setting for this. For me this is a problem. Please can you solve? , this is very unpractical and nonsense. Why changed this like that?
