@techguy1224 It may be a/the problem. For passwords synchronisation to work and for Opera to be able to decrypt the information, your Opera account needs to have a password.

@krteq Seems more like a bug or some visual effect that is nothing working as should .

I just opdated to Opera version: 128.0.5807.52

Now I can access the website again.
No particular change listed at https://blogs.opera.com/desktop/changelog-for-128/ seems to ring a bell, but I'm not complaining,

@burnout426 Eventually, I found out, that the problem is not associated with Opera but as you said, it only turned out when I used it. It's a problem with DNS resolving, indeed, but it was happening with Firefox or Brave as well.

My ISP advised me to make a complete reset, so I'll hope that the issues are gone now. Thank you for you help, nevertheless. You're advice is very welcome.

@slim54 Browser Assistant is not necessary, Opera can run fine without it.

How can I get rid of this website that keeps popping up when I open Opera?

@Jouron , while Claude has some excellent features but currently on its doc portal say the browser extension is not yet supported on other Chromium-based browsers.
