There are 2 versions of Adobe Flash: *an '''ActiveX version''' for IE only *a '''Plugin version''' for most other browsers including Firefox *On a Windows system, you should always update both individually. '''''You do not appear to have the Plugin version for Firefox installed. ''''' If you did, in Add-ons > Plugins you would see "Shockwave Flash ''(version)''". If "Shockwave Flash" is there and is disabled, click the "Enable" button.
