Does Firefox extends events page lifetime when I run a `fetch`?

Actually, does Chrome?
Or only internal API counts?
Looking at the docs: The extension service worker lifecycle  |  Chrome Extensions  |  Chrome for Developers

Events and calls to extension APIs reset these timers, and if the service worker has gone dormant, an incoming event will revive them.

MDN doesn’t mention (at least I can’t see it) what will prevent killing event page: Background scripts - Mozilla | MDN

No, not in Chrome: https://issues.chromium.org/issues/40827026

Not in Firefox, either, it looks like… You can use this line of code to test (run it slightly before the event page stops):

let response = await fetch(‘https://example.com:81/’).catch((e) => console.log(e));
