Opera Browser: Rating Login in new window problem with cookies

hi
When i want to rate an addon
https://addons.opera.com/de/extensions/details/getthemall-any-file-downloader/
there popups a new window every time. I told Opera to open new windows as tabs, but here it fails.
After Login this Login window closes automatically.
Then clicking on the stars there comes an error:
"Internal Server Error"

My diagnose: With addon "Self Destroying Cookies" all cookies were deleted after window closes.
But there are only following options for cookie delete: Tab, Window, never.
I do not want cookies to live forever.
And i dont want to deactivate SDC.
What can i do?

Wasn't it more practically not to open a new window for Login on the Addon page?

thx
