Once one of the most widely used technologies for displaying media-rich content on the web, Adobe Flash has been deprecated and has now made its exit from the internet. Although Mozilla disabled Flash in Firefox starting January 2021, as the platform reached its end of life, you can still use it if you need to access websites that rely on Adobe Flash. This tutorial shows you how to enable Flash in Firefox and allow it to run on the sites you trust:\r\n\r\n\r\n\r\nNOTE: This \u201cFirefox enable Flash\u201d tutorial covers Mozilla Firefox version 85 or newer.\r\nAdobe Flash Player is gone. What happens if you visit a Flash website in Firefox?\r\nIf you try to open a Flash website in Firefox, this web browser doesn\u2019t tell you anything about the fact that Flash has been discontinued. No Flash content is loaded, and no messages about it are shown. One doesn\u2019t even know that Flash content should have been there. In the example below, there should have been a Flash game - instead, all we got was complete and total nothingness.\r\n\r\n\r\n\r\nFlash Player Firefox: Disabled\r\n\r\nIn case you want details for why this happens, the Adobe Flash Player EOL General Information Page makes it clear the company \u201c[...] no longer supports Flash Player after December 31, 2020, and blocked Flash content from running in Player beginning January 12, 2021.\u201d\r\n\r\n\r\n\r\nAdobe Flash Player EOL 2021\r\n\r\nWhile it may look like you can no longer enable Flash in Firefox, there is a solution. Without further ado, here\u2019s how to allow Flash on Firefox:\r\n\r\n\r\nHow to enable Flash in Firefox\r\nThe best way to allow Flash Player in Firefox is to install and use a browser extension named Ruffle. As Ruffle is in development as we speak, it\u2019s not yet available on the Firefox Browser Add-ons website, so you have to install and activate it manually.\r\n\r\nUse Firefox to go to Ruffle\u2019s Releases webpage and download the latest Firefox / Edge / Safari browser extension. Don\u2019t just click on the link - right-click or press-and-hold on it, then select \u201cSave Link As\u2026\u201d from the contextual menu displayed.\r\n\r\n\r\n\r\nRuffle Flash extension for Firefox\r\n\r\nSave the Ruffle browser extension somewhere on your computer, like on your Desktop or in the Downloads folder.\r\n\r\n\r\n\r\nSaving the Ruffle browser extension for Firefox Flash\r\n\r\nBack in your Mozilla Firefox browser, type about:debugging in its address bar, and press Enter on your keyboard.\r\n\r\n\r\n\r\nabout:debugging page in Firefox\r\n\r\nOn the left sidebar, select This Firefox. Then, click or tap on the \u201cLoad Temporary Add-on\u2026\u201d button from the top-left area of the Extensions page.\r\n\r\n\r\n\r\nLoad Temporary Add-on in Firefox\r\n\r\nThe previous action launches a new window called \u201cSelect manifest.json file or .xpi/.zip archive.\u201d\r\n\r\n\r\n\r\nUse it to browse through your Windows computer or device to locate the folder where you saved the Ruffle Firefox extension. Once you\u2019ve found it, select it and press the Open button.\r\n\r\n\r\n\r\nLoading Ruffle Flash extension in Firefox\r\n\r\nFirefox should then immediately install and activate Ruffle. If everything works correctly, you can see it on the Temporary Extensions list.\r\n\r\n\r\n\r\nRuffle has been installed in Firefox\r\n\r\nFinally, try to visit a website with Flash content. Just like in our example below, Firefox should now be able to load Flash Player.\r\n\r\n\r\n\r\nFirefox enabled Flash using Ruffle\r\n\r\nThat\u2019s it! You\u2019ve managed to enable Flash Player in Firefox.\r\n\r\nIMPORTANT: In most cases, Ruffle is the answer to the \u201cFirefox enable Flash\u201d issue. However, don\u2019t forget that Ruffle is in an early development stage, and it doesn\u2019t yet support all types of Flash content.\r\nAre you still using Adobe Flash Player in Firefox?\r\nNow you know how to allow Flash on Firefox. However, as Adobe Flash Player finally reached the light at the end of the tunnel, most websites already migrated towards other technologies, such as HTML5. Fewer users than ever actually need to enable Flash in Firefox these days. Why are you still using Adobe Flash Player? Do you think Flash should have continued living?
