1266409 - service workers are disabled when setting "Never remember history"

Status: NEW

(Firefox :: General, defect)

Description

[Julian Descottes [:jdescottes]]

STRs:
- check navigator.serviceWorker is defined in webconsole
- open preferences
- go to privacy
- set History to "Never remember history"
- restart the browser as prompted
- navigator.serviceWorker is now false

Is this an expected behavior? 

If yes, UIs such as about:debugging and about:serviceworkers need to check this in order to display a message explaining service workers will not work with the current setting.

Dan, maybe you know the expected behavior here?

"Never remember history" is the same as always being in private browsing.
It sets browser.privatebrowsing.autostart to true.

Sorry for the delay in responding.

I don't know what the right behavior is, but based on :ochameau's response, adding a message to about:debugging and about:serviceworkers seems like a reasonable step.

Our user-facing ServiceWorker story in general is pretty rough, e.g. Bug 1253031 - Impossible to clear data cached by Service Workers through any exposed UI. I'll be working to get some traction on that this quarter.
