it's not working for me, for example this webpage www.olx.pl. Whenever you open a new tab from this site, there is service worker actived, but not only one! it does detected olx.pl service worker but it didn't detect other one wp.pl. and I only want to block this wp.pl service worker. it's somehow hide behind avoide detection Please help me out!

The allow/deny prompt should clearly state which domain attempts to register a SW. Example: I visit "website.com" which has an embedded youtube video on it. Both the website and youtube (via its iframe) attempt to register a SW, yet the extension only asks "allow or deny THIS worker?" -- I would like to block the youtube SW (which is a useless resource hog) but allow the website.com one. Thanks

Worked for me! (had an issue with a site whose service-worker was somehow outdated/not-updating, and this was the only thing that fixed the issue for me, so I could use the latest version of the site's/webapp's code)
