1141070 - "InternalError: too much recursion" in multiprocessShims.js upon calling nsIComponentRegistrar.registerFactory

Status: RESOLVED WONTFIX

(Firefox :: Extension Compatibility, defect)

Description

[Rob Wu [:robwu]]

Calling Components.manager.nsIComponentRegistrar.registerFactory (or unregisterFactory) causes the following error:

InternalError: too much recursion (resource://gre/components/multiprocessShims.js:130:8)
JS Stack trace:
  AddonInterpositionService.prototype.interpose/[e-mail]:130:9
  [e-mail]:291:5

This feature worked before, and the regression seems to be introduced by https://hg.mozilla.org/mozilla-central/rev/9f9ac2060b54 as a part of bug 1007982.

To confirm this bug:
1. Install https://github.com/Rob--W/nnnotifier/blob/e937ca4a63842af5215369410cb698607b14b5da/nnnotifier.xpi
2. Open the console (stderr or Ctrl + Shift + J).
3. Observe that SystemMessageCache: init1425900959215   addons.xpi      WARN    Exception running bootstrap method shutdown on [e-mail]: InternalError: too much recursion (resource://gre/components/multiprocessShims.js:130:8) JS Stack trace: AddonInterpositionService.prototype.interpose/[e-mail]:130:9 < [e-mail]:291:5 < AddonInterpositionService.prototype.interpose/[e-mail]:130:52 < ...

I worked around the bug using https://github.com/Rob--W/nnnotifier/commit/933c4aebdecd8e97fb8a0ebb6e3b8cf75534f8e4, but it would be nice to fix the bug, since other addons might also be affected. I looked around, and found https://github.com/mkiol/GNotifier/issues/39#issuecomment-66732140, for instance.

Mass-closing old Extension Compatibility bugs that relate to legacy add-ons or NPAPI plug-ins. If you think this bug is still valid, please reopen or comment.

Sorry for the bug spam, and happy Friday!
