Revisionsindhold
Sometimes, the video or audio content in a web page cannot be properly downloaded and displayed in Firefox. A required plugin may be missing, outdated, blocked, in conflict with another plugin or extension, or the content may be blocked for some reason. This article will help you solve these problems.

Flash videoer afspiller aldrig
Hvis Flash videoer ser sorte, hvide eller grå ud eller aldrig afspiller, så læs Flash 11.3 indlæser ikke video i Firefox.
Installer manglende plugins
Although Firefox can display some media on web pages such as images and open media like Ogg and WebM videos, it may need the help of media players and browser plugins for video, audio, and other content. Although you may have the correct media players installed to play video and audio files, you may be missing the necessary plugins when the media is embedded within the web page itself.
When a plugin is missing, do the following:
- Click on the download link.
- Then follow the instructions.
In case the installation fails, install it manually.
- Flash plugin: See Installer Adobe Flash Player til visning af animationer, video og spil and Flash Plugin - Hold det opdateret og fejlsøg problemer
- The Flash plugin is used for many types of embedded audio and video, including YouTube.com videos.
- Java plugin: Brug Java-plugin til at se interaktivt indhold på websider
- Silverlight plugin: See Afspil lyd og video med Silverlight plugin'et
- Windows Media Player plugin: See Afspil Windows Media-filer i Firefox med Windows Media-plugin'et
- The Windows Media Player plugin will only play a specific few Windows media formats (.asf, .asx, .wm, .wma, .wax, .wmp, .wmv, and .wvx) unless the web page is specifically designed for Firefox and other Mozilla browsers. Internet Explorer will use Windows Media Player for many other formats like mp3 and midi, but Firefox will require another plugin, such as QuickTime.
- QuickTime plugin: See Brug QuickTime plugin'et til at afspille lyd og video
- The QuickTime plugin can handle many different types of embedded media. On older operating systems, the QuickTime plugin may not be configured to handle some common file formats found online, such as embedded .mp3 audio on Windows XP or Mac OS X 10.5 and below. In such cases, you need to select the media formats you want QuickTime to play in Firefox in your QuickTime Preferences.
For other, less common, media players and their plugins, see these websites:
Opdater dine plugins
Check that you have the latest versions of all your plugins.
- Go to our Plugin Check page and follow the links to update any plugins that are out of date.
Tillad Plugin Holderen i dit Internet sikkerheds program
Allow your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) to trust plugin-container.exe also known as Plugin Container for Firefox. For detailed instructions, see Konfigurer din firewall, så Firefox kan få adgang til Internettet where in that case Firefox means Plugin Container for Firefox.
Deaktiver et plugin der skaber konflikt
If you have more than one plugin installed that can handle the same media type, this can cause a conflict that prevents some embedded media from playing. You may be able to fix the issue by disabling one of the plugins.
- Klik på menuknappen , klik på , og klik så på .
- In the list of plugins, select the plugin you wish to troubleshoot.
- If you want to disable the plugin, click the button.
- If you want to re-enable the plugin, click the button
- Klik på menuknappen , klik på , og klik så på .
- In the list of plugins, select the plugin you wish to troubleshoot.
- If you want to disable the plugin, select in its drop-down menu.
- If you want to re-enable the plugin, select in its drop-down menu.
For example, you may need to disable the VLC plugin to play embedded QuickTime or Windows Media content. For more information about troubleshooting problems caused by plugins, see the Fejlsøg problemer med plugins som Flash eller Java for at rette almindelige Firefox-problemer article.

Ryd cachen
Læs Sådan ryddes Firefox' cache.
Deaktiver forstyrrende udvidelser eller reklame-blokerings software
- Ad-blocking software, such as anti-banner filters of your Internet Security program, or extensions, such as Flashblock or Adblock Plus, can prevent audio or video content from playing. If the site works with ad-blocking disabled, you may want to add the site to your whitelist in your adblocker filter.
- Any Firefox extension can also block plugins. If the video or audio plays when you disable all extensions, then one of your extensions was causing the problem. For more information, see Fejlsøg udvidelser, temaer og hardwareacceleration for at løse almindelige Firefox-problemer.
Kontroller nogle Firefox indstillinger
- Verify that cookies are enabled in the Privacy panel in the OptionsPreferences window. Verify that the site is not blocked in the Cookie Exceptions list.
- Allow the website as an exception in the Firefox pop-up blocker. The "Block pop-up windows" option is found in the Content panel of the OptionsPreferences window.
- Verify that JavaScript is enabled in the Content panel of the OptionsPreferences window.
Fjern specifikke elementer i hosts filen (avancerede brugere)
If you use a hosts file, you can temporarily disable it by renaming it Xhosts. Or, you can edit the hosts file to remove specific entries such as ad.doubleclick.net that can cause videos on certain sites to fail (for more information, see this MozillaZine forum thread). To apply changes to your hosts file, you may need to flush the DNS cache by entering the command: ipconfig /flushdns
in the Run dialog box on Windows.
