Adobe Flash曾经是在网络上显示富媒体内容的最广泛使用的技术之一，现已被弃用，现已退出互联网。尽管Mozilla从^(Mozilla)2021 年 1 月^{(January 2021)}开始在Firefox中禁用Flash，但随着该平台的生命周期结束，如果您需要访问依赖Adob​​e Flash的网站，您仍然可以使用它。本教程向您展示如何在Firefox中启用^(Firefox)Flash并允许它在您信任的网站上运行：

注意：^(NOTE:)本“Firefox 启用 Flash”^{(“Firefox enable Flash”)}教程涵盖Mozilla Firefox版本 85 或更高版本。

Adobe Flash Player消失了。如果您在Firefox中访问^(Firefox)Flash网站会发生什么？

如果您尝试在Firefox中打开^(Firefox)Flash网站，则此 Web 浏览器不会告诉您有关Flash已停止使用的任何信息。没有加载Flash内容，也没有显示有关它的消息。人们甚至不知道Flash内容应该在那里。在下面的示例中，应该有一个Flash游戏 - 相反，我们得到的只是完整的和完全的虚无。

Flash Player Firefox：已禁用

如果您想详细了解为什么会发生这种情况，Adobe Flash Player EOL 一般信息页面^{(Adobe Flash Player EOL General Information Page)}明确表示公司“[...] 2020 年 12 月 31 日之后不再支持 Flash Player，并且从 1 月开始阻止 Flash 内容在 Player 中运行2021 年 12 月 12 日。”^{(“[...] no longer supports Flash Player after December 31, 2020, and blocked Flash content from running in Player beginning January 12, 2021.”)}

Adobe Flash Player 2021 年停产

虽然看起来您可能无法再在Firefox中启用^(Firefox)Flash，但有一个解决方案。事不宜迟，以下是在Firefox上启用^(Firefox)Flash的方法：

如何在 Firefox 中启用 Flash

在Firefox中允许Flash Player的最佳方式是安装和使用名为Ruffle的浏览器扩展。正如我们所说，由于Ruffle正在开发中，它尚未在Firefox 浏览器附加组件^{(Firefox Browser Add-ons )}网站上可用，因此您必须手动安装和激活它。

使用 Firefox 前往Ruffle 的 Releases 网页^{( Ruffle’s Releases webpage)}并下载最新的Firefox / Edge / Safari浏览器扩展。不要只单击链接——右键单击或按住它，然后从显示的上下文菜单中选择“将链接另存为...” 。^{(“Save Link As…”)}

用于 Firefox 的 Ruffle Flash 扩展

将Ruffle^(Ruffle)浏览器扩展保存在您计算机上的某个位置，例如您的桌面^(Desktop)或“下载^(Downloads)”文件夹中。

为Firefox Flash^{(Firefox Flash)}保存Ruffle浏览器扩展

返回Mozilla Firefox浏览器，在其地址栏中输入about:debugging ，然后按键盘上的Enter 。

在左侧边栏上，选择This Firefox。然后，单击或点击“扩展^(Extensions)”页面左上角的“加载临时加载项...”^{(“Load Temporary Add-on…” )}按钮。

上一个操作会启动一个名为“Select manifest.json file or .xpi/.zip archive.”

使用它来浏览您的Windows计算机或设备，以找到您保存Ruffle Firefox扩展的文件夹。找到它后，选择它并按“打开^(Open)”按钮。

然后Firefox^(Firefox)应该立即安装并激活Ruffle。如果一切正常，您可以在临时扩展^{(Temporary Extensions)}列表中看到它。

Ruffle已安装在Firefox中^(Firefox)

最后，尝试访问具有Flash内容的网站。就像^(Just)我们下面的示例一样，Firefox现在应该能够加载Flash Player了。

Firefox 使用 Ruffle 启用 Flash

就是这样！您已成功在Firefox中启用^(Firefox)Flash Player。

重要提示：^(IMPORTANT:)在大多数情况下，Ruffle是“Firefox 启用 Flash”^{(“Firefox enable Flash”)}问题的答案。但是，不要忘记Ruffle处于早期开发阶段，还不支持所有类型的Flash内容。

您^(Are)还在Firefox中使用Adob​​e Flash Player吗？

现在您知道如何在Firefox上允许^(Firefox)Flash了。然而，随着Adob​​e Flash Player终于走到尽头，大多数网站已经迁移到其他技术，例如HTML5。如今，真正需要在Firefox中启用^(Firefox)Flash的用户比以往任何时候都少。为什么你还在使用Adob​​e Flash Player？你认为Flash应该继续存在吗？请在下面的评论中告诉我们。

How to enable Flash in Firefox -

Once one of the most widely used technologies for displаying 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, аs the platform reachеd its end of life, you can still usе it if you nеed to access websites that rely on Adobe Flaѕh. This tutorial shоws you how to enable Flash in Firefox and allow it tо run on the sites you trust:

NOTE: This “Firefox enable Flash” tutorial covers Mozilla Firefox version 85 or newer.

Adobe Flash Player is gone. What happens if you visit a Flash website in Firefox?

If you try to open a Flash website in Firefox, this web browser doesn’t 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’t 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.

Flash Player Firefox: Disabled

In case you want details for why this happens, the Adobe Flash Player EOL General Information Page makes it clear the company “[...] no longer supports Flash Player after December 31, 2020, and blocked Flash content from running in Player beginning January 12, 2021.”

Adobe Flash Player EOL 2021

While it may look like you can no longer enable Flash in Firefox, there is a solution. Without further ado, here’s how to allow Flash on Firefox:

How to enable Flash in Firefox

The 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’s not yet available on the Firefox Browser Add-ons website, so you have to install and activate it manually.

Use Firefox to go to Ruffle’s Releases webpage and download the latest Firefox / Edge / Safari browser extension. Don’t just click on the link - right-click or press-and-hold on it, then select “Save Link As…” from the contextual menu displayed.

Ruffle Flash extension for Firefox

Save the Ruffle browser extension somewhere on your computer, like on your Desktop or in the Downloads folder.

Saving the Ruffle browser extension for Firefox Flash

Back in your Mozilla Firefox browser, type about:debugging in its address bar, and press Enter on your keyboard.

about:debugging page in Firefox

On the left sidebar, select This Firefox. Then, click or tap on the “Load Temporary Add-on…” button from the top-left area of the Extensions page.

Load Temporary Add-on in Firefox

The previous action launches a new window called “Select manifest.json file or .xpi/.zip archive.”

Use it to browse through your Windows computer or device to locate the folder where you saved the Ruffle Firefox extension. Once you’ve found it, select it and press the Open button.

Firefox should then immediately install and activate Ruffle. If everything works correctly, you can see it on the Temporary Extensions list.

Ruffle has been installed in Firefox

Finally, try to visit a website with Flash content. Just like in our example below, Firefox should now be able to load Flash Player.

Firefox enabled Flash using Ruffle

That’s it! You’ve managed to enable Flash Player in Firefox.

IMPORTANT: In most cases, Ruffle is the answer to the “Firefox enable Flash” issue. However, don’t forget that Ruffle is in an early development stage, and it doesn’t yet support all types of Flash content.

Are you still using Adobe Flash Player in Firefox?

Now 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?
