Does Blocking Site Notifications in Opera Also Block Service Worker Push Messages?

Question

GoalDetermine whether a site‑specific notification block in Opera suppresses push notifications delivered through service workers.ContextOpera’s Site Settings panel allows a user to set a site’s notification permission to Block. The UI does not distinguish between standard banner alerts and push messages sent via service workers. Clearing site data does not remove the block flag, indicating a persistent setting. The behavior of this block with respect to push notifications remains undocumented.Unresolved DecisionWhen a site’s notification permission is set to Block, does Opera also prevent the site’s service worker from delivering push notifications? If the block is persistent, does it apply to all future push attempts, even after the site’s data has been cleared?Specific QuestionsWill a Block permission on a domain suppress push notifications sent via service workers?Does clearing site data remove the block flag for push notifications, or does the permission persist independently?Is there a separate setting or API that can differentiate between standard notifications and push notifications within Opera?

AnswerYes, blocking a site’s notification permission in Opera also blocks its service‑worker push messages.Confirmed factsOpera treats the notification permission as a single flag that controls both visible notifications and push delivery via service workers.The block is stored persistently; clearing site data (cookies, cache, storage) does not reset the flag to its default state.Opera does not provide a separate UI or permission toggle for push notifications versus regular notifications.Verification stepsOpen opera://settings/content/notifications, add a test domain, set its permission to Block.Open DevTools → Application → Service Workers, register a service worker for that domain, and use the Push section to send a test push.Observe that no push event is fired in the service worker console.Clear site data for that domain via Settings → Privacy & security → Clear browsing data.Return to the notifications settings page; the domain remains listed as Blocked.Repeat the push test; the push is still suppressed.
