In Opera, you can goto the URL opera://settings/system and enable "DNS over HTTPS" and set it to Cloudflare to test if that helps.
Also consider that maybe there's an issue with the router itself but only Opera is able to expose it. If the router comes with your internet service, maybe you can get your ISP to replace it to see if that helps.
I've been getting something like this using Opera One version 127.0.5778.76 on my Win 10 laptop - in my case it doesn't remember whether I have allowed or blocked notifications for a site, just asks me each time I visit. I don't think I've encountered the camera/microphone or location permissions issue yet, but I don't really use websites that might need them.
В последнее время передачи в Ютубе стали прерываться рекламой, но реклама не загружается и блокирует сайт. Приходится вообще отключаться, потому что невозможно ждать, когда загрузится реклама, а иногда вообще рекламу невозможно отключить.
depois de muito estresse e ficar com a musiquinha na mente, achei onde desativa essa bexiga... é nas configurações do som do tema! é só clicar em editar e desabilitar.
