Build ID: 20151221130713
Steps to reproduce:
Even though I set some of my installed plugins to "ask-to-activate", they are still visible via `navigator.plugins` when they are not yet activated. This issue breaks my Baidu Drive page, since the page identified and tried to make use of a inactivated plugin. I have to disable some plugins completely to avoid page problems.
Actual results:
Please try this code below. You will see not-yet-activated plugins listed:
```html
<HTML>
<HEAD>
<TITLE>About Plug-ins</TITLE>
</HEAD>
<BODY>
<SCRIPT language="javascript">
numPlugins = navigator.plugins.length;
if (numPlugins > 0)
document.writeln("Installed plug-ins");
else
document.writeln("No plug-ins are installed.");
for (i = 0; i < numPlugins; i++) {
plugin = navigator.plugins[i];
document.write("<center><font size=+1><b>");
document.write(plugin.name);
document.writeln("</b></font></center><br>");
document.writeln("<dl>");
document.writeln("<dd>File name:");
document.write(plugin.filename);
document.write("<dd><br>");
document.write(plugin.description);
document.writeln("</dl>");
document.writeln("<p>");
document.writeln("<table border=1 >");
document.writeln("<tr>");
document.writeln("<th width=20%>Mime Type</th>");
document.writeln("<th width=50%>Description</th>");
document.writeln("<th width=20%>Suffixes</th>");
document.writeln("<th>Enabled</th>");
document.writeln("</tr>");
numTypes = plugin.length;
for (j = 0; j < numTypes; j++)
{
mimetype = plugin[j];
if (mimetype){
enabled = "No";
enabledPlugin = mimetype.enabledPlugin;
if (enabledPlugin && (enabledPlugin.name == plugin.name))
enabled = "Yes";
document.writeln("<tr align=center>");
document.writeln("<td>");
document.write(mimetype.type);
document.writeln("</td>");
document.writeln("<td>");
document.write(mimetype.description);
document.writeln("</td>");
document.writeln("<td>");
document.write(mimetype.suffixes);
document.writeln("</td>");
document.writeln("<td>");
document.writeln(enabled);
document.writeln("</td>");
document.writeln("</tr>");
}
}
document.write("</table>");
}
</SCRIPT>
</BODY>
</HTML>
```
Expected results:
Not yet activated plugins should not be visible via `navigator.plugins` for security reasons.
I guess this is impossible, if the sites does not find plugins, many existing sites probably will not use plugins and redirect to less functionality, such as HTML5 or "unable to browse" tip.
