hello, adobe has released a critical patch for a vulnerability in its flash plugin, which is reportedly already exploited in the wild. therefore firefox will block insecure versions from running by default on websites for your protection. https://helpx.adobe.com/security/products/flash-player/apsb14-27.html https://addons.mozilla.org/firefox/blocked/p794

please update to Adobe Flash Player version 16.0.0.235 as soon as possible, which you can download from http://www.adobe.com/products/flashplayer/distribution3.html (use the windows-exe for plugin-based browsers).

The Plugin check is behind on what versions is current to check for so it is useless at moment until it is updated.

This is because 15.0.0.239 is not the latest Firefox 15 version as there has been at least 15.0.0.242 which is on blocklist and 15.0.0.246 which is not on the blocklist as according to Adobe it is not affected.

Flash Player Plugin 14.0 to 15.0.0.242 https://addons.mozilla.org/en-us/firefox/blocked/p798

Flash Player Plugin 10.3.183.66 to 13.0.0.258 https://addons.mozilla.org/en-US/firefox/blocked/p794

So for Windows and Mac 16.0.0.235, 13.0.0.259 ESR and 15.0.0.246 are not vulnerable according to Adobe and are not on blocklist.

philipp you need to update your posting for this as Mozilla made a two part blocklist on Friday so as to not block the 13.0.0.258 ESR version and your link is for one of the two blocklists for Win/Mac.
