1862157 - Enable Service Worker debugging in DevTools by default

Status: NEW

(DevTools :: Debugger, task)

Description

[Alexandre Poirot [:ochameau]]

For now, you could only debug Service Workers right from DevTools when manually toggling the devtools.debugger.features.windowless-service-workers, or via the Firefox Experiments page.

This has been disabled because of significant performance regression when enabling this new capability.
Bug 1651522 should address the main performance bottleneck and we should then be cause to toggle this preference ON by default. And later remove this settings entirely.

The experiments page will soon move out of Nightly and be displayed on release/beta. We have been asked if this was ok for our devtools setting about "Service worker debugging". I assume it is the case since we are planning to enable the feature by default, but let's discuss in triage.
