Build ID: 20130410205058

Steps to reproduce:

In the "Scripts & Plugins" Advanced Preferences, enabled the "Activate all plugins by default" checkbox.  Then visited any website with inline video (eg. YouTube), and visited to play music.

Actual results:

1.  Areas where video player should appear on web sites displays grey box with "lego brick" icon and "Click here to activate plugin" text.

2.  Clicking the PLAY button (right-pointing arrow) on songs on does nothing.

Expected results:

1.  Video player should auto-activate for web sites with video, when above-mentioned checkbox is enabled.

2.  Music playback should begin on when clicking the PLAY button.

Set importance to "Major", since for some web sites (like ), there is no "Click here to activate plugin" widget, and therefore the site features remain impossible to use with SeaMonkey.
Severity: normal → major

Try turning this off.

Same thing.
The "Activate all plugins by default" setting, be it enabling it or disabling it, does not seems to change the web browser operation.

Just as you describe. Clicking PLAY (right-pointing arrow), the song plays inline.
Play, pause, jump & volume controls all working as expected.
Suppose you want a URL like:  or (better)
What plugins do you have?
Do you have Flash?
Anything blocking Flash (Flashblock or Noscript)?

Plugins installed and enabled:
Adobe Acrobat
Java Deployment Toolkit
Shockwave Flash 11.4.402.265

There are a few others that are all disabled (Java Platform SE6 U29, Microsoft DRM, Octoshape Streaming Services 20000.9.407.0, Windows Media Player Plug-in Dynamic Link Library, Windows Presentation Foundation 3.5.30729.1)

Extensions installed and enabled:
ChatZilla 0.9.90
DOM Inspector 2.0.14
JavaScript Debugger 0.9.89 Downloader

I did not add, remove, enable, disable, or change any of the plugins or extensions settings when this problem started occurring.
I also never changed the "Activate all plugs by default" setting in Preferences when this problem started occurring.
SeaMonkey does auto-upgrade itself, so I can only suspect the new version to which it upgraded has an auto-activation flaw that the old version did not have.

Your Flash is quite dated (& vulnerable).
Update to current (11.7.700.169).
Does the problem persist?

Restart in Safe Mode, does the problem persist?
(Help | Restart with addons disabled)

As a test, create a new, clean Profile.
Does the problem persist?

As a test, if you revert to an earlier version of SeaMonkey, does the problem persist?

Actually, your version of Flash is blocklisted:
Flash Player Plugin between 11.0 and 11.4.* (click-to-play) has been blocked for your protection.

Never confirmed by a second user, No response to Comment 6, Comment 7, so I close this one for now.

@Reporter: Please feel free to reopen this Bug if you still can reproduce the problem with a current SeaMonkey version, current plugin version and a current OS and if you can contribute a step by step instruction due to <>  (containing every key press and every mouse click) how to reproduce the problem reliably.
