It's too bad that one has to disable the feature to work around the problem.
</p><p>It used to just come on and stay on, and for most websites it still does, but I've been noticing this constant appearing/disappearing behavior now. There's definitely an active element to these pages that is confusing/abusing Firefox.
</p><p>Since I didn't want to deal with an extension I applied your solution by adding a crome/userChrome.css file to the Firefox profile directory containing the following:
</p><p>notification[value="plugin-hidden"] {
</p><pre> display: none&nbsp;!important;
</pre>
<p>}
</p><p>For those who don't know, the Firefox profile directory is located at:
C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\[profile]
where [profile] is a random string of letters and numbers.
</p><p>Perhaps now that this notification is constantly appearing and disappearing on many websites Mozilla will have to address the problem formally!

Perhaps what is happening is that those ads use a script to determine whether the media played, and if it didn't start quickly enough, it tries a different one??
</p><p>I must confess that my customizations may have shielded me from this problem:
</p><p>(1) I use the NoScript extension to block unimportant scripts in pages, so that may be removing lots of annoying advertising.
</p><p>NoScript isn't for everyone because it requires so much training; there are much more direct ways to block advertising. However, I need it for security reasons when investigating questionable websites.
</p><p>(2) For a while I've been completely hiding the bar using a custom style rule. I use the plugin notification icon on the address bar when I want to activate Flash (or should I say, when something I expect to play isn't playing).
</p><p>This is the rule, in case you are interested. I apply it to Firefox using the Stylish extension:
</p><p>@namespace url(http://www.mozilla<em>.</em>org/keymaster/gatekeeper/there.is.only.xul);
/* Hide Plugin Notification Infobar */
notification[value="plugin-hidden"]{
display:none !important;
}
</p><p>You can get various other recommendations for workarounds, but I just don't know if there is a real fix.
