@vegelund I'm having the same issue for years now.

Problem got fixed in the new update.

Hi everyone,

I noticed a problem with the Opera One. For example let's say you have two windows. And you are working in the first window. The problem is, whenever the URL changes in the second window, it jumps to the second window, and if url changes in the first window it jumps to the first window vice-versa. It's a really frustrating problem to be honest.

Example video of the problem:

(Note: I only press to ALT+TAB one time just after I opened a new window to change the link in first browser. Rest of the changes happened by itself)

My version is 100.0.4815.54 and I'm having the same problem for a while. Deleting entries is extremly hard and besides that history tab is problematic as while. Multiple times I come up to a empty page when I open the history page.

Hi everyone,

Whenever a download request came up, I want Opera to ask my permission to download it. I doesn't want opera to start to download unless I gave the permission to do it.

And I know that, it keeps downloading from the background even browser asks for where to put the downloaded file when you click to download button. So that's not the solution.

Thanks in advence!
