Abwarten: Das nächste Update auf Version 118 lässt sicher nicht mehr lange auf sich warten. Dann wird das Problem bestimmt behoben sein (und ein anderes auftreten )

Opera stable is still on Chromium 132, whereas actual Chromium is already on 134. Chrome, Edge, Brave and Vivaldi to my best knowledge are already as well. Is there a reason to be concerned or how does Opera handle security that comes with newer versions of Chromium?

There's a bug in this update which hasn't been there in the last updates before. It's also been talked about in the German language forum:
https://forums.opera.com/topic/83841/opera-suchleiste
The issue refers to the address bar. Whenever you open an URL in the address bar and then by clicking on the start page icon on the left side it brings you back to the speed dial but leaves the latest URL in the address bar. Expected behavior would be the address bar being empty. In this case you could simply click into it to type a new address. But that's not possible with this version any longer.
There should be a fix in due time. Thank you very much.

@mogwa Bei mir ist es genauso. Ist mir auch noch nie aufgefallen. Ich habe auch die Schnellwahl als Startseite.

@leocg Thank you for your comment. I'll look into this.

@leocg I also see this happening in my installation of Opera. I'm not sure if this really is something Chromium related, actually.
Third party cookies blocking works in Opera for Android e.g. as well as in Edge and Vivaldi with a more recent Chromium version, indeed.
I remember this to have happened with previous versions of Opera as well and being eventually fixed with an update. So I hope this will happen again with the jump to 118.
