Failed to register a ServiceWorker
kanneiren last edited by
I load the same extension in developer mode in both chromium edge and vivaldi.Both browsers are up to date. In edge,it works perfectly.But in vivaldi,it shows"Uncaught (in promise) TypeError: Failed to register a ServiceWorker ""An unknown error occurred when fetching the script."
What shoud I do?
As shown in image, Vivaldi complains about trying to load one of the extension scripts - without giving much info.
Vivaldi 3.6.2165.40 (Stable channel) (64-bit)

@Gwen-Dragon thanks. Still getting the same error after upgrading to:
Vivaldi 3.7.2218.55 (Stable channel) (64-bit)
@Gwen-Dragon I didn't change anything about the extension after downloading it from that link... any ideas of things that could be different with my system?
There is some kind of a bug in Vivaldi with the extensions, which are using Manifest Version 3.
The problem is with the new service worker which replaced background script .
I made multiple tests and workarounds but without success.
The results: service worker is started only when the browser starts. It is working for few seconds and then goes to inactive state .
This is the expected behaviour. Then the bug occurs.
The service worker never wake up again and we cannot start it anymore except with browser restarting.
I can recommend you to make a bug report as me.
My version is: Vivaldi 4.2.
I`m very pleased to tell you that this bug is fixed from Vivaldi (4.3.2439.63) and now the extensions with manifest V3 works normal in Vivaldi.
