@simb1973 did u sure not use opera block ads feature?

find the suspect and other user confirm this extension is malware when i want uninstall and check when this extension update.

no more new windows open new random page linkenid after i clear cokies.

i try this and check history after 2 hour and linkenid is gone

i got this too, and i cant reset my opera because some reason
so this my solution
using block site extension and set auto close when url linkenid

so the linkin website cant load in my browser.
