1696020 - Disabling service workers in about:config does not disable or unregister active service workers

Status: RESOLVED DUPLICATE of bug 1645054

(Core :: DOM: Service Workers, defect)

Description

[lucastronks]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Test if a compatible website gives you a notification when the website is not loaded.
This indicates a service worker is active and working. Go into about:config and set dom.serviceWorkers.enabled to false.
Test if you can still receive notifications from the website, the one that previously registered a service worker, while the it is not loaded.

Actual results:

You will still receive notifications from the website as the service worker is somehow still active.

Expected results:

You will not receive notifications from the website as the previously registered service worker functionality should have been disabled when you changed dom.serviceWorkers.enabled to false.

I would like to confirm your issue, so I need to ask:

• How exactly do you confirm that a compatible website gives you a notification when it is not loaded?
• Also, can you provide an example of a compatible website? Does this work?

Is this the exact action path you took?

1. Open the browser.
2. Go to about:config and flip dom.serviceWorkers.enabled to true (default)
3. Load https://serviceworke.rs/push-simple_demo.html
4. Click the "Try to conquer Italy!" button (no page loading involved)
   Observe: Notification is displayed.
5. Go to about:config and flip dom.serviceWorkers.enabled to false
6. Focus the previously test page loaded in step 3 (do not refresh)
7. Click the "Try to conquer Italy!" button (no page loading involved)
   Actual: displays a notification
   Expected: does not display a notification

Thanks!

Considering the fact that I believe I understood the reporter correctly and reproduced the steps described above, I will confirm this issue and let developers decide whether this is really an issue or actually not valid.

Clear a needinfo that is pending on an inactive user.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
