I tried adding ublock origin addon for opera, but after clicking on it, it says, can't open file.

I thought TV could open it, on inserting any usb pendrive. Even after inserting it, I saw the same thing. Can it be sideloaded by storing and installing file from google drive? Or is there any other way to block ads, as Opera's inbuilt ad blcoker seem to not block all ads? How are you blocking ads now?
