about:plugins lists blocklisted and user-disabled plugins
Because of bug 757726 (http://hg.mozilla.org/mozilla-central/rev/42b22f0ab58c ) about:plugins doesn't update the lists of disabled plugins from AddonsManager anymore. Manually reproduced: 1.Open Addons Manager 2.Disable a plugin 3.Open about:plugins Results: -plugin did not disappeared from about:plugins when disabled in Addons Manager as it should have.
Reason here is that we no longer filter by enabled plugins: http://hg.mozilla.org/mozilla-central/file/42b22f0ab58c/toolkit/content/plugins.html#l60 This regression has been found by Mozmill.
I'm actually happy with this change and think we should keep it. It's useful to be able to see the full version information for plugins even if they are disabled in the addons manager. The only think I would change is that we should show the enabled/disabled state in about:plugins. So I'm going to morph this bug.
Summary: about:plugins doesn't hide disabled plugins anymore → about:plugins should show the enabled/disabled state of plugins
This change causes a permanent test failure in our testsuite. It would be nice if we can get this fixed sooner than later. What does P2 mean? I just wonder if we should disable the test for the time being.
P2 means that somebody is working on it but it doesn't stop all other activity.
Here is a quick fix for the about:plugins regression. It skips "inactive" plugins, which includes both blocklisted and user-disabled. I assume the previous about:plugins implementation using navigator.plugins skipped blocklisted plugins, but I don't have any blocklisted plugins installed that I can test with. I agree with bsmedberg that about:plugins should show all plugins plus their enabled/disabled/blocklisted status, but I think fixing this about:plugins regression in the meantime makes sense.
Comment on attachment 702932 [details] [diff] [review] skip-inactive-plugins.patch Yeah, if this is easier we can do it for now. Can you file the bug I wished we had?
I filed bug 831533 to track the plugin status bug.
Chris, thank you for fixing it that quickly!

Mitza, please check in FF22 first; I think we probably fixed this in bug 830267. If you can still reproduce it there, then yes, file a bug.
Mozilla/5.0 (Windows NT 6.2; WOW64; rv:22.0) Gecko/20130412 Firefox/22.0 This is fixed on FF22 (Build ID:20130412004014), so I won't file a new bug.

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0 Build ID : 20130425162858 On FF21 Beta 5 the plugin is correctly shown in about:plugins with the state "Disabled" As for the Comment 14 after the Step 5 the plugin is enabled.
