There are 2 versions of Adobe Flash player; one for IE (ActiveX) and one for most other browsers including Firefox (Plugin). You do not appear to have Flash installed for Firefox (Plugin) on the system used to report your question (click "More system details" to the right of your original question, "Shockwave Flash" is not listed). You can check in your Firefox Add-ons > Plugins to see if "Shockwave Flash" is listed but disabled. When updating Flash on a Windows system with IE installed, you should always update both. Download (for your OS and browsers), save, close all browsers, run the installers that you just downloaded from the following page: *https://www.adobe.com/products/flashplayer/distribution3.html Also see - *https://support.mozilla.org/en-US/kb/install-flash-plugin-view-videos-animations-games *https://support.mozilla.org/en-US/kb/keep-flash-up-to-date-and-troubleshoot-problems *General plugins info - https://support.mozilla.org/en-US/kb/use-plugins-play-audio-video-games Check your plugins and update as needed - https://www.mozilla.org/en-US/plugincheck/
