When i use my adblocker on youtube this playlist sized blank space appears and pushes other videos down, Opera Team can you fix it?

When i download on Opera Developer it sometimes, just sometimes randomly crashes
When i go back it says my download failed but it actually downloaded and i can see it on my downloads page, but download that were in progress will indeed Fail.

Someone to take this away?
