Please update to the latest version of Flash, which is not blocked. https://get.adobe.com/flashplayer/

Firefox has not "dumped" the Flash plugin. After Adobe announced critical security flaws in version 18.0.0.203 and earlier, Mozilla "soft-blocked" those versions. What is that? Instead of letting all sites use Flash automatically, which was the default setting, Flash was temporarily switched to requiring sites to have express permission to use Flash, to help protect against "drive by" attacks. Adobe released an update a couple days later, and you can get version 18.0.0.209 on this page: https://www.adobe.com/products/flashplayer/distribution3.html In the first table, look for the row for "plugin-based browsers" and you can use either the EXE or the MSI installer. To ensure that the old version is removed, please close any tabs that are using Flash, or exit out of Firefox, during the update. ---- Now, even without the latest version, you have the choice to use Flash. If you are not accustomed to using the "Ask to Activate" feature with any of your plugins, here's how it works: When you visit a site that wants to use Flash, you should see a notification icon in the address bar and usually (but not always) one of the following: a link in a black rectangle in the page or an infobar sliding down between the toolbar area and the page. The plugin notification icon in the address bar typically looks like a small, dark gray Lego block. When the page wants to use a soft-blocked plugin, the icon turns red to alert you to the concern. If you see a good reason to use Flash, and the site looks trustworthy, you can go ahead and click the notification icon in the address bar to allow Flash. You can trust the site for the time being or permanently. But some pages use Flash only for tracking or playing ads, so if you don't see an immediate need for Flash, feel free to ignore the notification! It will just sit there in case you want to use it later.
