无法在Firefox上观看视频或播放音频？动画(Animations)不工作或图片(Pictures)不显示？如果Firefox 视频(Firefox Videos)、声音(Sound)、图片(Pictures)和动画(Animations)无法正常工作，那么这篇文章提供了解决问题的方法。您可能需要检查您的设置以及已安装的插件和扩展。
视频(Videos)、声音(Sound)、图片(Pictures)、动画在(Animations)Firefox中不起作用
我们将研究这些可能的解决方案：
- 修复(Fix)Firefox for Windows N版本的视频和音频播放问题
- (Fix Media)修复Firefox(Firefox)更新后媒体 插件停止工作
- 修复：图像未在 Firefox 中加载
- 图像质量看起来很糟糕
- 允许 Firefox 插件容器
- 启用 Flash Player 支持
修复(Fix)Firefox for Windows N版本的视频、音频播放问题
由于欧洲(Europe)严格的反竞争做法，微软(Microsoft)为该国维护了一个专用版本的 Windows “N”。它拥有除媒体(Media)播放器之外的所有内容，以及任何流媒体相关技术，包括Skype、Xbox等应用程序。
如果您使用的是Windows 10 N，则需要 从 Microsoft站点下载适用于 N 个版本的 Windows 10 的媒体功能包。(Media Feature Pack for N versions of Windows 10)此外，您应该下载媒体编解码器以在应用程序和浏览器中播放媒体：
这应该可以解决Firefox(Firefox)中的大部分视频和音频播放问题。如果您的问题特别是在 Youtube 上使用 Firefox 没有音频( no audio on Youtube with Firefox)，请查看 SoundFixer。
(Fix Media)修复Firefox(Firefox)更新后媒体 插件停止工作
某些媒体插件在Firefox 更新(Firefox Update)后停止工作，因为不再支持它们放置文件的位置。如果你想让它们工作，你需要启用一个设置。
- 在地址栏中输入 about:config，然后回车。
- 接受出现的风险警告。
- 接下来，搜索plugins.load_appdir_plugins 设置。
- 双击以启用它或将其设置为 true。
- 重启火狐。
也就是说，最好找到此类插件的替代品。大多数流行的媒体播放器（包括VLC）都安装了适用于浏览器的编解码器，并支持多种格式。
修复图像未在 Firefox 中加载
检查 Firefox 中的图像加载设置(Check image load settings in Firefox)
- 在地址栏中输入 about:config，回车，然后接受出现在下一个屏幕中的风险警告
- 搜索permissions.default.image。
- 右键单击，然后重置。
如果设置为 2，则表示图像下载已禁用。虽然 3 表示允许从同一网站加载图像，但要禁用 3rd 方图像。
检查特定网站的图像权限(Check image permissions for a specific website)
Firefox允许您阻止某些网站的图像加载，以加快页面加载速度。如果您在查看特定网站的图片时遇到问题：
- 单击(Click)站点标识按钮(Site Identity Button)。这是一个小圆圈，里面有“i”。
- 然后再次单击安全/不安全状态旁边的箭头按钮，然后单击更多信息。
- 这将打开页面信息窗口(Page Info window)。
- 切换到权限(Permissions)面板，并确保在加载图像(Load Images)权限旁边设置允许(Allow)。
- 关闭页面信息窗口。
图像质量很差
这通常发生在您使用互联网加速器软件时。这些软件会压缩图像，因此它们看起来都很糟糕和模糊。确保(Make)禁用此类软件。
如今，这些功能已内置于Internet Security 软件(Internet Security software)中。因此，如果您使用的是一个，请检查是否有特定于速度的设置可能是此问题的根本原因。
允许 Firefox 插件容器
Firefox现在带有一个插件容器，可以单独加载每个插件。即使插件崩溃(plugin crashes)，它也允许Firefox保持打开状态。由于它是单独运行的，因此互联网安全和Firefox可能会阻止它。检查块，与Firefox相关的任何内容都应设置为完全访问，并允许。
启用 Flash Player 支持
仍在使用Flash的网站会在您访问该网站时提示您启用支持。(enable the support)通常不推荐使用Flash(Flash)，因为它伴随着安全问题，但如果你需要启用它，这就是你的做法
- 转到 Adobe 的 Flash Player下载页面(download page)并下载 Flash 安装程序。
- 退出 Firefox，然后安装它。
- 启动 Firefox(Start Firefox)，然后转到插件(Plugins)部分。
- 始终激活 Shockwave Flash(Activate Shockwave Flash)或选择 要求激活。(Ask to activate.)
要求激活更好，因为它可以确保当(Ask)Flash中存在安全漏洞时，没有网站可以在您的计算机上下载恶意软件。
最后但并非最不重要的一点是，确保音频(audio is working on Windows)在其他地方的 Windows 上正常工作。有时我们会错过这个检查，而驱动程序问题(driver issue)就是它一直以来的问题。
Hope this helps!

Videos, Sound, Pictures, Animations not working in Firefox
We will look into these possible solutions:
- Fix video and audio playback problems on Firefox for Windows N version
- Fix Media plugins stopped working after Firefox update
- Fix: Images not loading in Firefox
- Quality of images look bad
- Allow Firefox Plugin Container
- Enable Flash Player Support
Fix video, audio playback problems on Firefox for Windows N version
Due to strict anti-competitive practices in Europe, Microsoft maintains a dedicated version of Windows “N” for the country. It has everything except for Media player, and any streaming related technology including apps like Skype, Xbox and so on.
If you are using Windows 10 N, you need to download Media Feature Pack for N versions of Windows 10 from the Microsoft site. Additionally, you should download media codecs for playback of media in apps and the browser:
This should resolve most of the problems of video, and audio playback in Firefox. If your problem is particularly with no audio on Youtube with Firefox, check out SoundFixer.
Fix Media plugins stopped working after Firefox update
Some media plugins stop working after a Firefox Update as the location where they place their files are no longer supported. If you want them to work, you will need to enable a setting.
- Type about:config in the address bar, and hit enter.
- Accept the Risk warning that appears.
- Next, search for plugins.load_appdir_plugins settings.
- Double click to enable it or set it as true.
- Restart Firefox.
That said, it’s best to find an alternative to such plugins. Most of the popular media player including VLC install codecs which works on browsers as well, and support a wide variety of format.
Fix Images not loading in Firefox
Check image load settings in Firefox
- Type about:config in the address bar, hit enter, and accept the Risk warning that appears in the next screen
- Search for permissions.default.image.
- Right-click, and reset.
If it was set to 2, then it means image download was disabled. While 3 means allowing images loading from the same website, but want to disable 3rd party images.
Check image permissions for a specific website
Firefox allows you to prevent images from loading for certain websites to make pages load faster. If you have trouble viewing images for a specific website:
- Click the Site Identity Button. It’s a small circle with “i” inside it.
- Then again click on the arrow button next to secure/insecure status and click on more information.
- This will open the Page Info window.
- Switch to the Permissions panel, and make sure to set Allow next to Load Images permission.
- Close the Page Info window.
Quality of images is bad
This usually happens when you are using internet accelerator software. These software compress images, and hence they all look bad and blurry. Make sure to disable such software.
Nowadays, these features are built into Internet Security software. So if you are using one, check if there is a speed-specific setting that might be the root cause of this problem.
Allow Firefox Plugin Container
Firefox now comes with a plugin container that loads each plugin separately. It allows Firefox to stay open even if the plugin crashes. Since this runs separately, the internet security and Firefox might have this blocked. Check on the blocks, and anything related to Firefox should be set to full access, and allow.
Enable Flash Player Support
Websites still using Flash will prompt you to enable the support when you visit the website. Flash is usually not recommended because of security issues it comes along with it, but if you need to enable it, this is how you do it
- Go to Adobe’s Flash Player download page and download the Flash installer.
- Quit Firefox, and install it.
- Start Firefox, and go to Plugins section.
- Activate Shockwave Flash for all the time or choose to Ask to activate.
Ask to activate is better as it makes sure no website can download malware on your computer when there a security flaw in Flash.
Last but not least, make sure audio is working on Windows at other places. Sometimes we miss on this check, and a driver issue is what it had been all the way down.
Hope this helps!
