Removing Services.jsm

[Tooru Fujisawa]

Hi everyone!

https://bugzilla.mozilla.org/show_bug.cgi?id=1667455 is going to remove Services.jsm and define `Services` global property on all privileged globals.
That means the statement like the following is no longer necessary (and doesn't work) once the patch lands.

const { Services } = ChromeUtils.import("resource://gre/modules/Services.jsm");

Also, sandboxes will get `Services` global property if `wantComponents` option is true (it defaults to true).

If there's any out-of-tree code that needs to support both before/after binary, you could do something like the following

const Services = globalThis.Services || ChromeUtils.import("resource://gre/modules/Services.jsm").Services;

A part of https://bugzilla.mozilla.org/show_bug.cgi?id=1667455 patch stack is going to be landed shortly, that removes all in-tree `Services.jsm` consumers,

while keeping `Services.jsm` file itself in tree, due to dependency from in-tree signed quitter.xpi (https://bugzilla.mozilla.org/show_bug.cgi?id=1777906).

The remaining patches that removes `Services.jsm` file will be landed shortly after the quitter.xpi gets updated.

Where is the bug that tracks the removal of the Services.jsm file?

There are still some out-of-tree uses of Services.jsm, and I'd like to make sure that there is an update plan for these before breaking these add-ons by the removal of Services.jsm.

Yes, https://bugzilla.mozilla.org/show_bug.cgi?id=1667455 is marked as leave-open,

and the Services.jsm removal is going to be landed there as well, as long as quitter.xpi update doesn't take long time

(otherwise it will be split into separate bug, to avoid spanning across releases).

About the out-of-tree consumers for Services.jsm, please refer https://bugzilla.mozilla.org/show_bug.cgi?id=1777486#c9

For privileged extensions, we've already submitted another announcement to authors, with privileged-extensions-specific info.
