We do have an option to turn off auto updates in the detail view of the OpenH264 plugin entry.
It looks like we don't honor the backing pref (media.gmp-gmpopenh264.autoupdate) for the initial download check though.

Brian, can you take this?

Comment 2

[Brian R. Bondy [:bbondy]]

Yep I can take this but I don't know of any pref that currently exists for this. You just want me to add a new one right? And it would be one pref per addon ID? (media.{full-id}.autoupdate)

Comment 3

[Georg Fritzsche [:gfritzsche]]

We do have the above-mentioned media.gmp-gmpopenh264.autoupdate pref - unset means "default", i.e. true, here.
The addon manager options for the OpenH264 plugin set this pref.

I assume we'll keep the pattern when we start supporting more GMP plugins, but it's hard to say for sure now.

-----------------------------------------------------------------

Can you add a test that no update/install happens for simpleCheckAndInstall() with the autoupdate pref off?
r=me with that.

[Brian R. Bondy [:bbondy]]

Ya I didn't because I don't currently have a test at all for simpleCheckAndInstall. I'll do this before landing though. Thanks for the review!

Carrying forward r+.

Changes for rev2:
- Added promise return for simpleCheckAndInstall
- Added 3 tests for simpleCheckAndInstall for the 3 cases which are not errors but that don't install addons.

Manual tests performed: 
- Ran xpcshell locally
- Verified addons off via addon manager leads to a log message that indicates that and no addon installed.
- Verified addons default via addon manager leads to a log message that indicates success and that addons manager reflects that too.

Approval Request Comment
[Feature/regressing bug #]: OpenH264

[User impact if declined]: Users will be unable to stop the browser from downloading a non-free plugin.  This is an issue of principle for some of our users, and might be a bandwidth issue for a few on very limited/shared or expensive connections.

[Describe test coverage new/current, TBPL]: Tested by QA.  In central for a week or so.  Includes several tests.

[Risks and why]: I believe the risk is low, but I'm not the expert on the frontend code.  From what I can see it's straightforward.

[String/UUID change made/needed]: none

Checked that automatic updates options work as expected before openh264 plugin is installed and after the plugin is installed. Tested on Windows 7 64bit, Ubuntu 14.04 32bit and Mac OS X 10.9.4 using latest Nightly and Aurora. Logs can be seen bellow:

[Richard Z.]

The whole update code is still broken. With Firefox 33 it will manipulate several pref values and mark them as "user set" in about:config.

Those are media.gmp-gmpopenh264.lastUpdate, media.gmp-gmpopenh264.version, media.gmp-manager.lastCheck

I think it is broken to abuse user preferences to store persistent variables.

Comment 15

[Georg Fritzsche [:gfritzsche]]

There is nothing broken with that. The preferences are used for storing state all over the place, "user set" just means "non-default value".
