[Metabug] Make Screenshots a regular, non-embedded webextension

last updated 12 Sep 2018

Metabug to track work needed to remove the bootstrapped wrapper from Screenshots:

Open items:

Lifecycle

• Check the disabled pref inside the webextension before loading the UI code (#4811)
  • The addons team did this for us, moving the disabled pref check into the browser (bug 1488971)
• Init the Library menu item from the webextension (#4812)
  • For now, the Library item is initialized via the embedded API. This will eventually be removed when the addons team allows webextensions to register Library items (bug 1483609)

Preferences handling

• short-term:
  • Use an API experiment to access about:config prefs (#4800)
  • Make sure we need the history.enabled check and, if so, check it from the webextension (#4531)
• longer term:
  • Replace prefs with storage.managed equivalents? (#4773)
  • Expose disable and disable-upload options in the about:preferences page? (#2711)

Uploads and ESR

• short-term:
  • Use an API experiment to check the update channel (#4802)
• longer term:
  • Check if platform is ESR from WebExtension (#4772)
    • this may require upstream work: https://bugzil.la/1386076
  • Add server version (necessary if ESR is allowed to upload; first step to ensuring older ESR clients can indicate they are submitting an older version of the upload packet) (#4775)
    • Note that, right now, we are sticking with the original policy of not allowing ESR to upload at all

Build related:

• Remove jpm and bootstrap references from Makefile / build tools
  • Ran into a weird error with jpm removal, leaving it in there for now (#4873)

Completed items:

• Remove startup delays (#3160)
• Remove migration code (#3844)
• Check Telemetry state & send Telemetry pings from WebExtension (#3713)
  • requires Telemetry API for WebExtensions (https://bugzil.la/1280234)
• Move Page Action code to WebExtension
  • landed in m-c directly as https://bugzil.la/1466575

The BMO dependencies are also tracked in the BMO bug: https://bugzil.la/1422437

Landed the webextension PR in #4864. Individual follow-up bugs have been filed for all the stuff marked 'longer-term' in the description. Closing ^_^
