Is the plugin listed and enabled on chrome://plugins ?

No, neither of the plugins are listed. However some other ones are there:

Adobe Flash Player

Chrome Remote Desktop Viewer

Native Client

Chrome PDF Viewer

Java(TM) (disabled)

Silverlight

I'm not the only person with this problem:

I'm also affected by this issue.

At work I'm developing a plugin. Since today, when I got upgraded to 23.0.1271.64 (Official Build 165188) m, our plugin is not detected anymore on 2 of the computers in our office. Other plugins on my machine are also not detected anymore, including Google Voice, Quicktime, Unity3D and some Yahoo Messanger State plugin.

I only see the following 7 plugins in Chrome's chrome://plugins as opposed to 16 in Firefox's Tools/Addons/Plugins:
Adobe Flash Player - Version: 11.5.31.2
Location:       C:\Program Files (x86)\Google\Chrome\Application\23.0.1271.64\PepperFlash\pepflashplayer.dll

Windows Media Player - Version: 1.0.0.8 (Disabled)
Location:       C:\Program Files (x86)\Mozilla Firefox\plugins\np-mswmp.dll

Chrome Remote Desktop Viewer
Location:       internal-remoting-viewer

Native Client
Location:       C:\Program Files (x86)\Google\Chrome\Application\23.0.1271.64\ppGoogleNaClPluginChrome.dll

Chrome PDF Viewer
Location:       C:\Program Files (x86)\Google\Chrome\Application\23.0.1271.64\pdf.dll

Adobe Reader - Version: 10.1.4.38 (Disabled)
Location:       C:\Program Files (x86)\Adobe\Reader 10.0\Reader\Browser\nppdf32.dll

Java(TM) - Version: 6.0.370.6
Location:       C:\Windows\SysWOW64\npdeployJava1.dll

Looking with Process Monitor from SysInternals I can see that chrome.exe is enumerating the MozillaPlugins registry key and is finding our plugin and npgoogletalk.dll and is even doing successful CreateFileMapping and Load Image operations on them.

I found an entry in HKLM\Software\Wow6432Node\MozillaPlugins\@java.com/DTPlugin,version=1.6.0_37 which has a Path key with a value of C:\Windows\SysWOW64\npdeployJava1.dll which would explain why the Java plugin above gets loaded. However HKLM\Software\Wow6432Node\MozillaPlugins has more entries, including our plugin and they don't get loaded.

If I change the Path of HKLM\Software\Wow6432Node\MozillaPlugins\@java.com/DTPlugin to an invalid value (change the dll extension to test for example) than I get 11 plugins instead of 7 in Chrome, so certain entries in MozillaPlugins can influence whether other entries get loaded or not. The 11 entries are the 7 above without the Java one I just disabled, plus these:

Google Talk (2 files) - Version: 3.10.2.10212
Location:       C:\Users\catalin.CEBRA\AppData\Roaming\Mozilla\plugins\npgoogletalk.dll
Location:       C:\Users\catalin.CEBRA\AppData\Roaming\Mozilla\plugins\npgtpo3dautoplugin.dll

QuickTime Player (7 files) - Version: 7.7.2 (1680.56) (Disabled)

Java(TM) - Version: 6.0.230.5 Download Critical Security Update
Location:       C:\Program Files (x86)\Mozilla Firefox\plugins\npdeployJava1.dll

Google Update - Version: 1.3.21.124
Location:       C:\Users\catalin.CEBRA\AppData\Local\Google\Update\1.3.21.124\npGoogleUpdate3.dll

VirtuoCity 2.6 - Version: 2,6,0,8
Location:       C:\Users\catalin.CEBRA\AppData\Roaming\VirtuoCity Browser Plugin 2.6\NPV3DComponents.dll

The last one is an older version of our plugin. However, this is still not the complete list, Unity, our newer versions of the plugin and the Yahoo plugin are still missing. Presumably another one of the entries in this new list is blocking the others. Any idea why the presence of the C:\Windows\SysWOW64\npdeployJava1.dll would stop Chrome 23 from loading other plugins?

Since this affects our company's product I'm highly interested in getting it solved as soon as possible so I'm available for anything you want me to test or extra information you want me to provide.

Here are 2 logs for starting Chrome with --debug-plugin-loading --enable-logging --v=1 and loading chrome://plugins in the 2 cases:

* 7 plugins listed because npdeployJava1.dll in in the registry in MozillaPlugins
* 11 plugins listed because I renamed npdeployJava1.dll to npdeployJava1.dll.test in the registry


If I diff the 2 logs they look quite similar but both of them have:
[1784:828:1114/160139:ERROR:plugin_list.cc(395)] Loading plugin C:\Windows\SysWOW64\npdeployJava1.dll
and then these suspicious looking messages:
[1784:828:1114/160139:ERROR:plugin_list.cc(395)] Loading plugin disabled
[1784:828:1114/160139:ERROR:plugin_lib_win.cc(28)] Could not get version info for plugin disabled

Interesting. In both cases, we inspect the same set of plug-ins, but renaming Java somehow removes the other plug-ins. And looking for a file "disabled" is also weird, although that might just be garbage in the registry.

Indeed, the "Loading plugin disabled" message appears because in HKLM\SOFTWARE\Wow6432Node\MozillaPlugins\@microsoft.com/GENUINE I have a Path with a value of disabled.

So all in all, the logs don't seem to show anything wrong. Is there more logging that I could enable?

After https://crbug.com/chromium/147634 was merged into this one, I want to make sure it is noted that Silverlight does not work at all in chrome 23.

Vivian, could you file a separate bug for the Mac issue? I have a fix, but it's for a Windows-only bug.

Chrisobrien89, can you elaborate? I know that not everyone can reproduce that Silverlight is broken, so if your issue is not Windows-only, please also file a new bug.

windows 8
23.0.1271.64

Microsoft Silverlight is installed on my computer and works with other browsers. Silverlight does not appear in the list of plugins, and any site that uses silverlight (such as netflix) says it is not installed.
I only have access to Windows, so I could not say if it occurs on other systems. This was already detailed in https://crbug.com/chromium/147634, but it was merged into this one.

Ok, that looks like it's this issue, so it's being taken care of :)

I reinstalled windows on an unrelated matter, before i installed Chrome, I installed silverlight first. After doing this I noted silverlight as indeed in the plugins list, and netflix is working.

Hi I am having a similar issue with the plugins. It started after upgrading to windows 8. I am not in metro ui and none of the plugins load.

I tried it with v23 and v25 but I had no luck with neither of them.

I have a fix for it that should land soon.

In the mean time, you can work around this issue by uninstalling unnecessary plug-ins. In your case, it looks like you have two versions of the Adobe Reader plug-in installed (D:\Program Files\Adobe\Acrobat 10.0\Acrobat\Air\nppdf32.dll and C:\Program Files (x86)\Adobe\Reader 10.0\Reader\Browser\nppdf32.dll), so you could try uninstalling one of them, which is not a bad thing in general.

Remove PluginList::RemovePlugin() and directly remove old plug-ins from plug-in list instead.

In the old version, removing the plug-in would modify the contents of the passed in parameter (which is a reference!), so we would keep on removing other plug-ins after it. Face, meet palm.

Aha. :) Uninstalling acrobat reader fixed my problem. Thank you Bauerb. I had tried everything.

Great to see that it's solved!

Do you have an estimate when the fix will be available in an update that is pushed to everybody? I would say it should qualify for inclusion in 23.something since it potentially affects a lot of people and a lot of plugins.

Not sure if we can get it into an M23 update, but M24 should be out soon :) I think it qualifies as a stable release blocker for 24.

Also, the fix is super-easy :)

Once QA verifies the fix in tomorrow's canary, I'll approve the merge.

Thanks! It's a bit tricky to verify (or reproduce) if your system doesn't happen to have the right configuration of plug-ins though, as you need to have two different versions of the same plug-in installed. Ping me if you need help.

Works fine in the current canary - 25.0.1329.0( Official Build 168464)

Works fine using 24.0.1312.25 (Official Build 169562)

Should we try to merge this back to 23?

Any idea about the likelihood of being hit by the bug (this seems to be triggered by multiple versions/instances of the same plugin)?

siedeen: any significant clusters on this issue from Google Feedback?

We did see reports of this issue in M23, but for the Silverlight plugin.
Pageviews to this main forum thread is ~100/day, so if the fix is safe to be merged, we should do it.

bauerb@: is this safe enough for a merge to M23? If yes, can you add the right label?Thanks.

Sure, the fix is almost trivial.

ok sg pls merge to 1271

The way I fixed mine was to download Chrome beta at https://www.google.com/intl/en/chrome/browser/beta.html

Or you could download Canary
https://www.google.com/intl/en/chrome/browser/canary.html

Everything I want to do can be done in Canary. I installed both of them. Silverlight works in both. My Facebook thumbnails still won't open with a click in beta but they will in Canary.

And now the beta version is working for Facebook. Go figure.

Works fine with 23.0.1271.97, Verified using bug using Steps provided in initial bug report.

The DivX Web Player is also not working for me, I think also since version 23. I can't watch these Twit videos for example:

http://twit.tv/show/this-week-in-tech/395

And I think some Flash videos weren't working either. I've noticed it on tumblr, and also on Twit before when they had another Flash/HTML5 player. It never worked on Flash, and it would only work when I was switching to the HTML5 player.

It's been 2 new versions since this started happening. Please fix this already! The videos work fine on Firefox.

Version: Version 42.0.2311.22 beta-m
OS: WIN 7 professional 64bit

What steps will reproduce the problem?
1. Go to http://www.microsoft.com/silverlight/iis-smooth-streaming/demo/
2. Try to play the video
3. You get an interstitial that says you need to install silverlight (which is already on the computer)
4. You try to install Silverlight again
5. Going through the Silverlight process fails because it says you already have a version of it
6. Try to watch the video on Chrome again and it still claims that you don't have Silverlight.

Note: I don't see Silverlight showing up in about:plugins

Locking. This is an old bug, about version 23, and totally unrelated to the recent NPAPI deprecation (https://www.chromium.org/developers/npapi-deprecation)
