Acrobat - Plugin Is Vulnerable and Should be Updated

We have encountered two issues recently, the first is that we have users who are getting the "This plugin is vulnerable and should be updated." message for the Adobe Acrobat plugin.

They have the latest version of the plugin. We use the Classic Track of Adobe Acrobat DC Pro. http://www.adobe.com/support/downloads/product.jsp?product=1&platform=Windows Users have the latest version - 2015.006.30198 from 7/12/2016 - and are getting this error message.

No update is available.

Some users are able to click to allow the plugin to run, some are not. And when clicking to allow the plugin to run, it's only an "allow once" action, there's no option to "allow and remember". When users are going through hundreds of PDFs, this is an issue.

Our second issue relates to the launching of the plugin itself. It seems that some users have an issue where the click-to-play functionality doesn't work. Clicking on the icon to allow the Acrobat plugin does nothing. Some users get a brief screen flash. No dialog to allow or allow and remember comes up. Additionally, the left of the URL bar does not show the plugin icon.

Refreshing doesn't change anything, but renavigating to the page - clicking into the URL bar and then hitting Enter - causes the page to reload and the plugin icon to show up on the left of the URL bar. Click-to-play functionality then works as expected - the allow or allow and remember dialog renders and, ultimately, the plugin runs and the PDF renders.

This is all on Firefox 47.0.1 on Windows 7. This happens only for some users. Testing on one user's machine that exhibited the issue revealed that the issue is not profile-specific. I created a new Windows profile on the machine, launched Firefox and did the first-time setup ("Don't import anything"), and then navigated to a PDF on the web. Click-to-play failed as described, and renavigating to the page (click into URL bar, Enter) fixed it.

hi conker, i think that may be an issue with the recent blacklisting of vulnerable versions of acrobat which includes the classic track by accident: https://addons.mozilla.org/en-US/firefox/blocked/p1247 i updated the bug to make mozilla devs aware of that...

As of today, it's working properly.

We still have users experiencing the other issue, however.
