How to detect if a plugin is waiting for permission?
I have a instance of a NPAPI plugin which is created using the embed element. I need to call some of the functions of the plugin when the page is loaded (<body> onload function) but all the calls fail since the user needs to first allow the plugin to load. When do I know that the user has allowed the plugin to be loaded? Is there a callback which notifies that a plugin can be used?

With the last Firefox upgrade, some plugins are no longer enabled until you enable it.
Open the Add-ons Manager. Press the <Alt> or <F10> key to bring up the tool bar. Followed by;
Windows; Tools Linux; Edit Mac; application name
Then Add-ons.
Hot key; <Control> (Mac: <Command>) <Shift> A)
On the left side of the page, select Plugins.
BTW; At the top right is a link to check your plugins.
Mozilla is changing the Plugin API and will be eliminating plugin support in the future.Plugins are now considered a "legacy technology".

The advice in that article about making the plugin visible is really important — and a backwards compatibility problem with sites that show a JPEG preview in front of the Flash player that gets cleared one the video loads. Sometimes the only way I realize the problem of video never playing is if I use
View > Page Style > No Style
since that turns off the style rules that overlap the two elements. Hmm...
Hi szanto.cosmin, I think you will need to test for the method before trying to invoke it. You may want to display a message to the user if it isn't available, or use window.setTimeout() to monitor for when the plugin is available.
@cor-el I'm trying to set a script callback to determine when a plugin is activated, but the callback is never called. Here's a simple example in which I reproduced my case.
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
</head>
<script type="text/javascript">
function pluginCreated() {
alert("Plugin created");
}
</script>
<body>
<object id="client" type="application/x-test">
<param name="callback" value="pluginCreated()">
</object>
</body>
</html>
