Attempting to open a .pdf with Firefox 18.0, and having Foxit Reader Plugin for Mozilla 2.2.3.111 installed, I receive the gray lego piece page with text "The plugin is vulnerable and should be updated/Check for updates/Click here to activate the Foxit Reader for Mozilla plugin" I look into the blocklist.xml file and find the plugin item: <pluginItem blockID="p250"> <match name="filename" exp="npFoxitReaderPlugin\.dll" /> <versionRange minVersion="0" maxVersion="2.2.1.530" severity="0" vulnerabilitystatus="2"></versionRange> </pluginItem> Next, I view installed plugins and find: Foxit Reader Plugin for Mozilla 2.2.3.111, and it is not disabled. My first question is why, when the installed plugin version is 2.2.3.111, and the blocklist maxVersion is 2.2.1.530, do I receive any kind of plugin blocked page? My second question is "is there any method or technique so specifically unblock a particular plugin, without affecting any other plugin?" I force-reinitialized the blocklist.xml file and database. Currently, I am running extensions.blocklist.enabled false, to sidestep this exact problem, but would definitely prefer to have this set true. Thanks.
