As an extreme multi-tabber, I often have multiple tabs open that show the same page/url.

A function that closes those duplicates in one go would be handy.

For me (on Opera developer) add blocking in YT started to work again, a couple of days ago.

I has the same issue on Opera One(version: 99.0.4780.0). on one website (marktplaats.nl) the option to turn on add blocking is even greyed out. Add blocking on YouTube is working now, but has been intermittently working lately.

I sometimes manually scale the Opera video pop-out to (near) full screen size on a second monitor. The task bar always stays visible and it can't be scaled to full size or larger than full size for some reason. (I use Windows 10)

I would like to suggest an option to scale the video to true full screen, so the task bar will no longer be visible. In Windows it would be great if Windows key + up arrow combination could be used for this, like is possible with other applications.

The parts of the screen that would contain no video because of the difference in aspect ratio between the screen and the video should be filled with black.

I use both Opera stable as Opera Developer at work. Because my roaming profile was getting larger and larger it took almost 15 minutes to log in. When I investigated the cause I found out that more than 7 Gb of Opera related files were sitting in these locations:

C:\Users\####\AppData\Roaming\Opera Software\Opera Stable[/Developer]\Service Worker
C:\Users\####\AppData\Roaming\Opera Software\Opera Stable[/Developer]\Code Cache
C:\Users\####\AppData\Roaming\Opera Software\Opera Stable[/Developer]\Local Storage

Before I deleted the files in those locations my Opera Developer also had trouble starting up. Sometimes I had to start it multiple times (and having to kill the hung processes in Task Manager) before it finally started up. This also seems related to the huge number of files in my AppData folder.

My question is: is there a way to automatically limit the storage space used by Opera to prevent these problems? Or to cleanup these files periodically instead of having to do this manually?
